Local LLMs running fully on device means user data never hits a server. No API calls, no logs, no third party agreements. For devs building sensitive apps, this isn't just a trend. It's the architecture shift we actually needed.

Not every widget needs its own file, fam. Splitting obsessively kills context. Sometimes keeping related widgets together is just cleaner code. Read the room, not the rulebook.

Clean Architecture in Flutter is mid for most apps. You're not building Google Maps. The extra layers just mean more files, more boilerplate, and slower shipping. Sometimes the real move is knowing when NOT to over-engineer.

Stop copy-pasting try-catch across every Flutter service. A Dio interceptor catches network and HTTP errors (timeouts, 401s, 404s) in one place. Just remember: it's your first line of defense, not the only one.

Do you use flavors? Yes | No 👇

Putting your Future inside FutureBuilder's build method restarts the task on every rebuild. Each build call creates a new Future object, and FutureBuilder compares by reference, so a new instance means a fresh start. Fix: initialize it once in initState(), store it in a field

Skipping dispose() on controllers and un-cancel()ed stream subs is how leaks hit prod. The order matters: dispose/cancel everything you own first, then super.dispose() last, never touch this after super runs. leak_tracker in tests catches the rest.

Using BuildContext after an async gap without a mounted check ships crashes to prod. Debug catches it; release burns users. The fix: if (!mounted) return in State, if (!context.mounted) return elsewhere (Flutter 3.7+). Better yet: don't pass context across async

SliverList shines in CustomScrollView for complex UIs. But for a simple list? ListView.builder is easier and wraps SliverList internally anyway. Use Slivers directly when composing SliverAppBar, SliverGrid, or SliverPersistentHeader combos.

Curious, what coverage percentage do you aim for in your codebase? Or do you even write tests at all? 👇

Half your pubspec solves problems the SDK already handles. HTTP? dart:io has HttpClient built in. Animations? AnimatedContainer, AnimatedCrossFade, no deps. Add only what's needed!

Flaky mobile sessions aren't always the network. Often it's retry logic. Back off 2^n sec with jitter, cap at 3. Retry only transient failures: timeouts, 5xx, 429 (429 is a 4xx). Skip the other 4xx. And only retry idempotent calls, or a timed-out POST can double-fire.

Diving into a completely new SDK and programming language can be intimidating 🫣 See how @redbrogdon used a multi-agent loop in @antigravity to quickly get up to speed on Python/ADK and build a Flutter frontend for deep research! → goo.gle/4p3gNm6

Deep links dying on cold start? Order, not luck. On applinks, uriLinkStream delivers the cold-start URI and every link after, but only if you create AppLinks() (a singleton) early. Route through gorouter. Create it late and the first link's gone.

Most search bars spam the API on every keystroke. Debouncing fixes that, but it's only half the job: async responses can arrive out of order and clobber fresh results with stale ones. The fix is debounce + a sequence guard so the newest query always wins.

Profile in debug mode. Numbers are okay. Run it in profile mode on a real device, see the real deal. Debug is JIT + asserts, intentionally slow, and it buries your real hotspots in the noise. Profile mode on a device is the only perf that's real

MaterialIcons-Regular.otf is ~1.6MB. Flutter tree-shakes it to a few KB (99%+) in release builds, keeping only glyphs you use. Hit a 'non-constant IconData' error? Don't use --no-tree-shake-icons, that re-ships 1.6MB. Fix the icon instead.
