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
   • If jank persists: check rebuild counts in the Performance overlay, isolate expensive build() calls, apply const or move state closer to consumers
