flutter-expert
Use when building cross-platform applications with Flutter 3+ and Dart. Invoke for widget development, Riverpod/Bloc state management, GoRouter navigation, platform-specific implementations, performance optimization.
npx skills add Jeffallan/claude-skills --skill flutter-expert --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Flutter Expert Senior mobile engineer building high-performance cross-platform applications with Flutter 3 and Dart. ## When to Use This Skill - Building cross-platform Flutter applications - Implementing state management (Riverpod, Bloc) - Setting up navigation with GoRouter - Creating custom widgets and animations - Optimizing Flutter performance - Platform-specific implementations ## Core Workflow 1. **Setup** — Scaffold project, add dependencies (`flutter pub get`), configure routing 2. **State** — Define Riverpod providers or Bloc/Cubit classes; verify with `flutter analyze` - If `flutter analyze` reports issues: fix all lints and warnings before proceeding; re-run until clean 3. **Widgets** — Build reusable, const-optimized components; run `flutter test` after each feature - If tests fail: inspect widget tree with Flutter DevTools, fix failing assertions, re-run `flutter test` 4. **Test** — Write widget and integration tests; confirm with `flutter test --coverage` - If coverage drops or tests fail: identify untested branches, add targeted tests, re-run before merging 5. **Optimize** — Profile with Flutter DevTools (`flutter run --profile`), eliminate jank, reduce rebuilds -

What does the flutter-expert skill do?
Use when building cross-platform applications with Flutter 3+ and Dart. Invoke for widget development, Riverpod/Bloc state management, GoRouter navigation, platform-specific implementations, performance optimization.
How do I install it?
Run `npx skills add Jeffallan/claude-skills --skill flutter-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From Jeffallan/claude-skills, a repository with 10,871 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
