Version managers like FVM, nvm, pyenv and SDKMAN are great at installing versions. None of them tells you that you have six Flutter SDKs, three Android NDKs and a 13 GB emulator you haven't started in a year. Stackyard does.

It shows every SDK, toolchain and framework version on your computer, which projects use each one, and what's safe to remove. Then it fixes what's wrong with one click, and nothing is deleted without you seeing it first.

Features

• Set up in a minute. On first launch Stackyard finds the folders where your projects live, shows how many projects each holds, and lets you add more.
• One window for every tech. A sidebar entry appears only for techs found on your machine.
• Get tools. A marketplace of SDKs and CLIs (Flutter, Android command-line tools, Node.js, Python, Java, .NET, Go, Rust, Deno, Bun, Gradle, and the Angular, Expo, NestJS, Firebase, Vercel, Ionic, Nx, TypeScript, pnpm and Yarn CLIs). Every version is listed from the publisher's own release feed. Downloads come straight from the publisher and are checked against their published hash. Before installing, you choose the folder and which environment variables to set (PATH, JAVA_HOME, GOROOT…): your user variables or everyone's on Windows, a marked block in ~/.zprofile on macOS. Installed versions can be made the default or removed later, which cleans up their variables too.
• Knows who uses what. It reads .fvmrc, .nvmrc, package.json, gradle-wrapper.properties, build.gradle, local.properties, .python-version, global.json and more across your project folders.
• Problems come with a fix button. Missing versions a project needs, two setups fighting over a folder, a broken JAVA_HOME: each is explained in plain words, with a button that fixes it. You never type a command.
• Environment doctor. Finds JAVA_HOME / ANDROID_HOME pointing at folders that are gone, dead and duplicate PATH entries (it saves a backup first), and a Java that's too new or too old for a Flutter app's Gradle and Android Gradle Plugin.
• Project cleanup. Shows the node_modules, build, .dart_tool, .gradle, Pods and other rebuildable folders in your projects, with a one-click clean for projects you haven't touched in months.
• Emulator manager. Start, cold boot, wipe data, delete snapshots or delete each Android emulator, with its size and when it last ran.
• Simulators (macOS). Every iOS, watchOS, tvOS and visionOS simulator with its size and last start: start, shut down, erase or delete it. The Xcode page shows each simulator runtime (often 8 GB each), which simulators use it, and Xcode's rebuildable caches.
• Progress you can see. Every install, removal and fix runs in Activity with its live output and a real progress bar. Cancel stops it cleanly, without leaving half a download behind.
• Safe removal. Things go to the Recycle Bin / Trash by default, or you can choose to delete permanently. Installed programs are removed with their own uninstaller. Links are removed as links; what they point to is never touched. You see every step before it runs, and a spinner wherever work is happening.
• Runs in the background. Closing the window keeps Stackyard in the system tray (Windows) or menu bar (macOS). It checks your setup daily or weekly and notifies you only when there's something new. It can start at sign-in.
• Move your setup. Export your toolchain versions to a file and import it on another computer to install what's missing.
• Never edits your projects. It doesn't change a project's pinned versions, because that can break builds.
• Native feel. Windows 11 Fluent design with Mica and your accent color; on macOS, the glass sidebar and motion of a Mac app. A Glass slider sets how much of your desktop shows through.

I had to render multiple high-res images in a grid layout for my Flutter app, so I went deep down the optimization rabbit hole. For some reason, I was getting crazy jank out of nowhere, even though I was using lazy-building lists (SliverList, ListView.builder, etc.), and had already implemented proper image resizing and caching.

Turns out, if you're using the flutter_svg package, setting the Impeller engine to renderingStrategy: .raster gives you a massive performance boost. But when I tested it on Skia, the picture strategy actually performed way better, total opposite results! Keep in mind I only tested this on Android, so iOS might behave differently.

Also, the default scrollCacheExtent is set to 250, meaning off-screen images were being processed even when I didn't explicitly touch it. Dropping that to 0 made a huge difference in performance. Turns out, optimization options built for convenience can sometimes bite you in the ass.

Another thing: ScrollAwareImageProvider is applied by default whenever you use an Image widget. It defers decoding while scrolling, but instead of waiting until scrolling completely finishes, it starts decoding even while scrolling is still ongoing if the scroll speed slows down a bit, which ironically causes major jank during the scroll itself. And guess what? You can't turn it off via options. I had to build a custom widget to fix it.

Anyway, if your grid items involve SVG or lots of images, optimizing them like this makes a world of difference. It pretty much eliminated stuttering even in 120Hz environments, and honestly, it’s mind-blowing how much of a difference it made. The performance gap was way bigger than I expected, so I figured I’d share.

Sync was the hardest part of my Flutter app by far. Most of my bugs were around auth, migrations, reconnecting, offline changes and getting two devices to agree.

The app is Personal Planner, a free planner for Linux, Android, Windows and macOS: hour-by-hour Day view with timers, daily and weekly reviews, a consistency heatmap, Experiments and an Inbox. First Flutter project for me.

How it's put together:

- **Local first.** Drift on SQLite is the everyday store. Moving a block, finishing a task, starting a timer or opening an old day never waits on a server

- **A local outbox.** Anything that still needs to sync waits there until the connection is back, and a sync engine pushes it to Supabase PostgreSQL

- **Supabase Auth** for sign-in, Riverpod for state

- **Provisioning.** A usable Supabase project needs the right schema, migrations, access rules and client config, and doing that by hand is painful. So a Cloudflare Worker does it from inside the app: connects your Supabase account, reuses a compatible project or creates one, applies the migrations and verifies the schema. Setup has several steps, so Durable Objects keep its state in between. After that the Worker is out of the picture and the app talks to Supabase directly

Two things I hit on desktop:

- On Windows, setup failed with CERTIFICATE_VERIFY_FAILED. Windows didn't trust the root certificate needed to reach Supabase, and updating Windows plus \certutil -generateSSTFromWU roots.sst` fixed it`

- The \com.personalplanner.personalplanner://` link scheme isn't registered on Windows and macOS yet, so the sign-up confirmation email and the provisioning authorization links can't open the app there. Email and password sign-in works fine`

Windows and macOS are built and smoke-tested on GitHub Actions. Both are unsigned, and macOS is CI-only because I don't own a Mac.

I tried quite a few libraries to run GGUF models on Android, but none really matched my expectations.

Apple's ecosystem feels more unified for on-device ML, with Core ML and MLX. On Android, the options and guidelines feel more scattered, and getting different models running without extra hassle isn't always straightforward.

So I decided to build Kiln, which is a C inference layer built on top of llama.cpp, with language bindings for Flutter, Kotlin, React Native, and more. It's too easy now to run a model with kiln.

The goal is simple: make running local AI models on mobile less painful.

It's open source, and I'd love to hear what other developers think or what could be improved.

It's available in pub dev too: kiln_flutter

Flutter is obviously a mobile-first platform due its origins, but I've spent 18 months using it to build a full-featured desktop application for Windows and macOS, with Linux planned.

I'm a developer with 20 years of experience, including desktop software development. This isn't a "build a todo list!" demo or a vibe-coded experiment: it's a substantial application approaching public release, and I thought Flutter developers might be interested in seeing what's involved in taking Flutter beyond mobile.

So what kind of desktop experience can Flutter build today? Here's one example. [See below for a link to get and run it yourself if you're interested. Free and open to anyone.]

The application is Fractal Outliner, a desktop outliner in the same general category as OmniOutliner for Mac, but focused for people who live mainly in plain-text ecosystems (e.g. sofware developers).

This is a desktop-only application. There is no mobile version. The goal is to provide a proper desktop editing experience with all that implies, integrated with the operating system rather than simply presenting a mobile-ported interface in a desktop window.

Flutter as a development platform was good for some parts of this, less good at others.

What the application is:

• Outliner with topics, subtopics; create, move, rearrange, hide to collapse, expand to drill down, move topic trees between documents, etc.
• Full keyboard support, with configurable shortcuts
• Integration with OS file handling, including file-type associations and opening documents from Finder/Explorer
• Drag and drop
• Document themes, including a custom theme editor
• PDF, HTML, Markdown, OPML, and plain-text import/export
• Multi-pane editing and tabbed documents
• Native desktop file operations and clipboard integration

What Flutter provided

Most of the application is built using Flutter's standard capabilities:

• Widgets and layout -- the main window content
• Keyboard event handling
• Shortcut registration and management
• Resizable windows and responsive layouts
• Drag and drop
• Context menus and right-click interaction
• Localization (English, Spanish, German, Japanese)

An effort was made to adapt the application to Mac and windows UI sytles; the experience is a little different on each platform (how dialogs work, what buttons and checkboxes look like, how settings are laid out, what menu items exist, etc).

What packages provided

Pub.dev packages filled in some of the functional gaps to extend Flutter's rending core:

• Markdown, XML, and HTML support
• Path handling
• PDF export
• Windows Store MSIX packaging
• macOS menu bar integration (with limitations)
• File pickers
• ZIP archive support
• OS and version detection
• Split view widget for multi-pane editor, etc
• Various other utilities (application uses 23 pub.dev packages total)

What flutter provides that works less well on desktop

• Keyboard event support: the model is there, everything technically works, but managing complex input focus and keyboard-based navigation using Flutter's FocusNode system is full of problematic edge cases
• Mac menu support, and general integration of menus + shortcut keys: the Mac menu integration is primitive, and windows and Mac use completely different menu+shortcut systems in flutter
• Printing: there's a pub.dev package for printing, but it requires exporting to PDF (challenging in itself with anything but simple font handling) and flutter provides no direct integration or visibility with the host printing system
• Undo/redo support: flutter's undo/redo implementation is self-contained inside each TextField, and there is no support at all for integrating text editing undo events with application-level events into one undo stream

What I implemented myself with native code

Flutter is just not a complete desktop development framework. It does great at drawing content in a desktop window. It does considerably less well at being a well-behaved and full-featured citizen in the desktop environment. A large number of things people expect from any desktop "document editor" application simply don't exist (or exist only in limited/problematic pub.dev packages) and have to be implemented with native code to get the best version:

• Remembering and restoring the window position and size, including enforcing a minimum window size
• Opening documents through the OS, such as double-clicking a file in Finder or Explorer
• Handling the file reference when the application is launched by double-clicking a document
• Document icons and file-type registration for the application's .frac files
• Spellchecking in text fields (available in Flutter's mobile text fields, but not built in to the desktop experience in the same way)
• macOS App Store sandboxing and file-access permissions
• An in-app command to show a document in Finder or Explorer
• Serious multi-format clipboard integration (vs basic plain-text copying and pasting flutter provides)
• Handling read-only files
• Various other OS integration details

The macOS App Store sandboxing and file-access work, in particular, is a lovely little nightmare. So are the limitations of the mac menu bar system integration, and the behaviors of Flutter's keyboard event handling and input-focus systems, dealing with international fonts in the PDF package, ... but those are stories for another day.

Other factors

• Internationalization
• Help files, etc

Internationalization to German Spanish and Japanese took far longer than for a mobile app, due to the larger set of "outside the application UI" resources used by the application (example files, templates, website content, video captions, etc). Also the usual trade-offs of "localize as you go" vs "localize at the end": early lets you see the impact of different text lengths in design (especially German/Spanish) which can be more severe with the wider range of window sizes on desktop, but usually means multiple re-do's of localization as UI and terminology evolve.

Help files and such are also more challenging on desktop, where applications can tend to be more complex and require more extensive help and reference materials as a baseline user expectation

Try it yourself

The application is now in its third beta release and nearing public release (latest version: 0.9.3 for Mac, 0.9.5 Windows). The public beta is open, free to use, and includes all application features. No registration or account is required.

If you're curious about Flutter on the desktop, you can try it on Windows or macOS and see how it works in practice.

Website and beta access: https://fractaloutliner.app

I'm interested in discussion with other Flutter developers about desktop development: what Flutter handles well, where its abstractions stop being sufficient, and what you've found necessary to implement through native platform code.

[Edits: typos]

If you’re building a video calling or streaming app in Flutter, these are the things that trip people up:

Mistakes to avoid

• Skipping TURN. About 15-20% of sessions can’t connect directly, and those calls stall with no error.
• Testing only on Wi-Fi. Test on 4G/5G and across Wi-Fi-to-cellular handover too.
• Using mesh for group calls. It breaks down around 4-6 users because every phone uploads to every other participant. Plan for an SFU from the start.
• Ignoring background behavior. You need CallKit on iOS and a typed foreground service on Android.
• Asking for camera/mic permissions at launch. Ask at the call screen instead.

Flutter notes

• Flutter WebRTC wraps the native iOS/Android libraries, so nothing runs in a JS engine.
• Our ant_media_flutter package has 5 samples (publish, play, peer, conference, data channel) and also targets Web and Desktop.

The SDKs are free, but playback and conferencing need the Enterprise edition of the server. Community Edition falls back to HLS, with 8-12s latency.

Full guide: https://antmedia.io/how-to-build-a-webrtc-mobile-app/

What’s been your biggest pain point with WebRTC in Flutter?

Disclosure: I work at Ant Media, and we wrote this guide. The advice applies to any WebRTC backend, though.

FrameX is an open-source developer utility and on-device security audit suite for Android package inspection and static vulnerability analysis.

• Static Security Analyzer: Flags cryptographic flaws, insecure api usage and leaks using advanced hardcoded secret detection.

• APK Package Inspector: Explores internal directories, DEX headers, byte breakdowns, and app signatures without unpacking to disk.

• Flutter Packages Scanner: Automatically scans compiled Flutter binaries to list third-party open-source packages.

• Privacy-First: Operates with zero ads, zero tracking, and 100% offline local processing.

Edit : GitHub Repository

Hi everyone

I'm conceptualizing a feature where users can completely transform an app or web interface using custom, downloadable "RPG-themed" extension packs from official repositories.

The core idea revolves around:

External Theme Plugins: Allowing users to download theme files (e.g., JSON-based configuration packs) from an official website and import them seamlessly.

Advanced Color Gradients: Implementing a dynamic color engine that smoothly transitions and interpolates complex color palettes defined by the user or the plugin.

RPG UI Metaphors: Structuring the design tokens to mimic fantasy/RPG interface elements without breaking performance.

From a software architecture perspective, what is the best way to safely parse external theme plugins, handle dynamic color tokens, and apply them across components without causing performance bottlenecks?

I'd love to hear your thoughts and technical recommendations. Constructive feedback is very welcome!

Hey all,

I'm trying to understand what everyone else is doing with in-app chats if you need to integrate it? Do you guys usually build it yourself or integrate something that already exists?

I've tried both but things get complicated very quickly with multi-device unread counts, typing and presence, read receipts, and moderation.

Where do you land: roll your own on Firebase or Supabase, or run a separate backend? What has worked for you, especially for keeping unread counts in sync across devices?

Hey everyone,

I recently got laid off, and with the current job market tightening up—fewer new projects and heavy competition for mid/senior roles. I’m taking a hard look at where to steer my career next.

I’m weighing three distinct directions and would appreciate candid advice and reality checks:

1. 1. Double down on Flutter & Mobile
   • Is Flutter still a dependable primary specialization for the next 3–5 years, or is it becoming too risky on its own?
   • I’ve been exploring full-stack Dart with Serverpod to broaden my skill set, but realistically, the job market for it is practically non-existent since it's so new.
   • For those sticking with Flutter, what viable adjacent skills are you adding (e.g., traditional backends like Go/Node, system design) to stay competitive?
2. 2. Pivot toward AI Engineering
   • Hiring reality: Do companies actually hire "AI Engineers" who don't have prior professional ML/AI experience, or do they mostly require senior backend backgrounds or advanced CS/math degrees?
   • Roadmap & entry point: Coming from a Flutter dev background, what does a practical, hireable roadmap look like? What specific tech stacks, core concepts (e.g., Python backends, RAG, tool calling, agentic workflows, evals), and resources would you recommend to build a job-ready portfolio?
3. 3. Switch to React (JS/Native) or Native App Development (Kotlin/Swift)
   • UI architecture, state management, mobile lifecycles, and performance optimization are fundamentally similar across frameworks, so this feels like the most direct way to leverage my existing Flutter experience.
   • Hiring reality: How do recruiters and hiring managers view this transition? Do they treat mobile/frontend fundamentals as transferable, or do resume screens filter you out for lacking "X years of commercial React / Kotlin / Swift experience"?
   • Where to focus: Between the React ecosystem (React.js + React Native for broader web/cross-platform volume) and Native (Kotlin/Swift for deeper platform specialization), which path has proven more practical for devs leaping recently?
   • What’s the fastest, most effective way to prove competence without commercial experience in those exact stacks?

Has anyone here successfully navigated a pivot from Flutter to AI engineering or React/Native recently? Any roadmaps, project ideas, or harsh truths would be greatly appreciated.

I've been doing Flutter for about 5 years and for the last 6 months Claude Code has written most of our app. I still review everything, coderabbit / claude review catch the obvious stuff first and I read what's left, so it's not like nobody looks at it.

Yesterday a user reported that the checkout screen freeze on older Android phones and I opened the file and genuinely didn't recognize it. 1,400 lines, three different state approaches in one widget tree, a Riverpod provider I had never seen before that apparently I approved in August.

I ended up asking the agent to explain my own screen to me. It fixed the freeze in ten minutes, which made it worse somehow.

The app is about 80k lines now and I think I could explain maybe a third of it.

Is anyone else maintaining a Flutter app they didn't really write?

Hi Flutter community! 
I'm a beginner in Flutter and I've been learning how to implement widgets and state management and more while building some hands-on projects.

I'm eager to dive deeper into Flutter and mobile dev in general. Any recommendations for good books, blogs, or video tutorials to help me keep growing?

Hi there, I'm a software developer and this is my first time using Flutter. As of today, I've made a lot of progress on a mobile game, but I'd like to know how far Flutter can be pushed. Do you guys know of any games built with it on the Play Store, or any famous ones?

I’m going to say what a lot of people are quietly thinking while nodding along in code reviews: Modern Dart/Flutter architecture has completely lost its mind.

We’ve reached a point where we take two simple booleans and a string list, and wrap them in a global singleton with a late ticking time bomb, shove them behind a cryptic three-dot-spread set-literal {...targets} where the meaning of a curly brace depends on a missing colon, and call it "clean, idiomatic functional programming."

Let's be completely honest for a second:

• If your language forces you to use late final because your initialization architecture is broken, that’s not "power", that’s a design flaw.
• If a single typo in a pair of curly braces changes the entire logic of your code from a map to a set, that’s not "elegant syntactic sugar", that’s a trap for humans.
• And if your solution to state management is forcing every developer to use a global singleton because injecting dependencies properly is apparently too much work for the framework designers, that’s just lazy architecture masked as "best practices."

Stop pretending this is genius engineering. Sometimes, a language doesn't need a whole fleet of workaround-constructs to do what a simple struct or a plain configuration file could do in 1995.

Change my mind. (Or downvote me to oblivion because you're too deep in the Google cult to admit it).

I just shipped Boba Sort, a water-sort puzzle (bubble tea, 500 levels, 17 eras of Japanese history) built with plain widgets and CustomPainter, no game engine. A few things that worked, and a few trade-offs, in case they help someone.

**1. All the art is data, not images**

There are no image assets at all. Each era has a full-screen scene, a cup design, a mascot costume and a customer, and I design them as SVG inside an HTML mockup. A small Python script reads named SVG groups and writes Dart lists:

final jomonBackdrop = <VShape>[

VCircle(292, 190, 54, fill: Palette.jomonSun),

VPath('M0 330 Q60 262 132 300 Q206 236 276 288 ... Z',

fill: Palette.jomonFarMountain),

...

];

`VShape` paints fill then stroke, like SVG, and `VPath` parses the `d` string once and caches the `Path`. All 17 eras × 4 kinds of art come to about 240 KB of generated Dart, stay sharp on any screen, and colors can only come from named palette entries (the script refuses anything else).

Because scenes sit behind the cups, a test renders every backdrop and checks each pixel's luminance stays inside a window (light eras ≥ 0.662, dark ≤ 0.0395), which keeps the cup outlines at ≥ 7:1 contrast wherever the cups land.

**2. Toppings: draw the vector once, then blit sprites**

Each drink has a topping (pearls, grass jelly, red bean...) drawn as vector art, and the top-layer pieces drift idly. A full board can have 200+ pieces, and redrawing that much vector art every frame is wasted work. So each topping is rasterized once per size into a `ui.Image`: sizes are bucketed to 4 physical px, kept in a 48-entry LRU (a plain insertion-ordered Map: remove + re-insert on hit, evict and `dispose()` the first key), and each frame just draws images.

**3. The rules are pure Dart, and an A* solver does the heavy lifting**

`lib/core` never imports Flutter: model, rules, level generator and solver are plain Dart with unit tests. The solver is A*, with each cup packed into one int (8 bits per layer) so states hash fast.

The 500 levels are generated offline: deal random cups, solve, score difficulty from moves, dead ends and branching, keep the median of 8 candidates, or the hardest of 32 for the "hard" levels in the sawtooth curve.

Hint uses the same solver at runtime, on the UI thread, with a 100k-node budget (about 0.4 s worst case in debug). Every bundled level is generated under that budget, so Hint always works from the start. One surprise: "Add cup" makes hints much slower, since an extra empty cup blows up the branching, so the hint search drops surplus empty cups first and only searches the full board if that finds nothing. If I raised the budget I'd move it to an isolate.

**4. A test that fails on magic numbers**

Every spacing, font size, radius and color is supposed to come from tokens. A test scans `lib/features` and `lib/theme` and fails on raw numbers inside `EdgeInsets`, `SizedBox`, `fontSize`, `BorderRadius` and `Color(0x...)`, with an escape hatch: a `// tokens: allow — <reason>` comment. Painters are exempt, since their numbers are geometry. It is a dumb regex-and-parentheses scanner, but it kept the UI consistent through a lot of screens.

**Stack:** Riverpod (thin providers), shared_preferences, google_mobile_ads, Firebase Analytics / Remote Config / Crashlytics, audioplayers.

Play Store, if you want to see the result: https://play.google.com/store/apps/details?id=com.harbourlab.bobasort&referrer=utm_source%3Dreddit_flutterdev%26utm_medium%3Dsocial%26utm_campaign%3Dlaunch

Happy to go deeper on any part. I'm curious how others handle heavy CustomPainter scenes.

Hey everyone! 👋

I've been working on SyncForge, an open-source synchronization toolkit for Dart and Flutter, and I'd love to get feedback from other developers here.

One of the challenges with offline-first apps is handling what happens when users make changes without a connection, multiple devices edit the same data, or an app needs to recover queued writes after restarting.

SyncForge is my attempt to make that synchronization layer modular and reusable instead of rebuilding it for every project.

The project consists of three packages:

- "sync_engine" — A pure-Dart core with vector clocks, CRDT primitives, conflict-resolution strategies, and a retryable outbox.

- "sync_engine_drift" — Persistent storage using Drift/SQLite, including outbox durability and tombstone tracking.

- "sync_engine_generator" — Code generation for strongly typed synchronization adapters using "build_runner".

The architecture is designed around pluggable storage and transport, with retry backoff, jitter, and dead-letter handling.

📦 Package: https://pub.dev/packages/sync_engine

💻 Source code: https://github.com/Wolfof420Street/flutter_sync_engine

📖 Architecture and examples: https://billodida.dev/projects/syncforge

It's still early-stage, so I'm not presenting it as a battle-tested production solution. I'm looking for developers who are interested in offline-first architecture and willing to challenge the design, try the examples, or point out gaps.

I'd particularly appreciate feedback on three things:

1. Would you use a reusable sync engine like this, or do you prefer implementing synchronization within each application?

2. What would you want to see before trusting a library like this with real application data?

3. Which conflict-resolution or synchronization scenarios do you think are hardest to get right?

Constructive criticism is very welcome. I'm building this in the open and would love to learn from developers who've dealt with synchronization in real projects.

Thanks for taking a look! 🙌

Hi all,

We've just released 1.0 of our universal_bluetooth_classic Flutter plugin, a Bluetooth Classic package that works across Android, iOS, macOS, Windows & Linux.

iOS developers in the house might be aware that using Bluetooth Classic on iOS is no picnic. It requires peripherals to be MFi-certified, and the whole communication has to go through Apple's EAAccessoryManager. As far as I can tell, universal_bluetooth_classic is the only plugin that supports Bluetooth Classic on iOS.

We have been using it in production for a while now so you can consider it battle-tested. Happy to receive issues and PRs.

If instead you are looking for a Bluetooth LE plugin you can have a look at universal_ble which just hit 3.0!

So there is a challenge going on with an app in my local area, The owner of the app said that if anyone can find a code he mentioned, in the app he will give u 300$ his app is a services app will u can find people to do a service for u, so what do guys think where the code is located in the app ? he posted this for public not Developers so i assume its easy its laying there somewhere in the Ul or maybe u need to search something in the app so the code comes up from the database?, ive uploaded the Apk file to claude but no luck, What are some ways i can use to find this code ?

the app is developed with flutter

Hello, I'm the author of the code_forge package, a very powerful text field widget capable of handling even 1M+ lines of text smoothly, where the default TextField widget crashes the app for a few thousand lines.

The package backend was written in rust using the ropey and zed_sum_tree crates, resulting in no web support and requiring the user to install rust in their system to build the package. Because of that most of the people migrated to an alternative package called re_editor.

I removed the rust backend and implemented rope data structure and zed_sum_tree like Layout mapping in pure dart.

Shipping a Flutter app means making assets for two stores. I made a free browser-based set of tools for that:

• Icon generator: AppIcon.appiconset + Android mipmaps/adaptive icon in one ZIP
• Splash screens incl. the Android 12 splash icon
• Screenshot maker for App Store (6.9") and Google Play sizes
• Privacy policy generator (covers AdMob/Firebase)

https://appnimbus.net

Everything runs locally in your browser. I know flutter_launcher_icons exists. This is for people who prefer a visual tool or need store screenshots too. Feedback welcome!

I’ve been working on Argent, an open-source MCP server that lets your agent (Claude Code, Codex, Cursor, etc.) use your app on the iOS/Android/web. It can tap through flows, read logs and network calls, take screenshots, aaaaand many more 😂 That way it can check its own changes instead of just saying it’s done

I know I know, it comes from the React Native world and we have some beef 😅 But this one is truly cross-platform and works with Flutter apps too! If you’re letting an agent drive your Flutter app, what’s working, and where does it fall apart? We really want to keep improving it for every framework!! 🤭

Hey Flutter builders!

I’m one of the co-founders of Nowa (https://nowa.dev), and we recently launched a version that lets designers inside Flutter teams design directly on the Flutter codebase instead of in Figma. This way developers can work on logic/data in parallel while designers build the full design and experience themselves, all in the same Flutter repo.

We’ve been designing Nowa inside Nowa itself for a while without talking much about it, since our focus was making Nowa an app-building platform for people who don’t know Flutter. Then a few companies pushed us to make this use case public, and now we’re considering making it our full focus.

So the way it works that Designers connect Claude Code, Cursor or Codex to Nowa through MCP, import the Flutter repo itself, and design with AI with full visual editing. They set up the design system directly in Nowa which reflect it in the Flutter repo, test different states for each UI component, build and share prototypes that feel like the final version, and own the full experience with things like animations.

To make that work, we came up with an architecture we called “PureUI”. It splits UI and logic into two separate packages, similar to MVI but more decoupled, with a small contract that defines how they work together: the “data” and the “actions”.

Designers import the UI package into Nowa and work on it, while developers work on logic/data in the logic package using their IDE and AI agent. Things like state management stay under the developers’ control as well.

So I’d love to hear from Flutter devs here who work on Flutter teams: does this problem exist on your team, and what could we do differently to make this more useful for your case?

Any input or opinion is highly appreciated!

I am looking for the framework I will make my mobile app with and a huge requirement is that I need it to be small in size. I've been looking at Tauri apps and they are consistently under 70 MB. Can Flutter match or beat that (Lowest I've seen is 53 MB)
