- Run requires Twitch credentials: `flutter run --dart-define=clientId=YOUR_ID --dart-define=secret=YOUR_SECRET`
- After changing MobX stores or `@JsonSerializable` models, run `dart run build_runner build`. Never edit `.g.dart` files directly. Use `--delete-conflicting-outputs` if the build fails on stale generated files. Commit `.g.dart` files to source control.
- The secure storage cleanup in `main.dart` looks unnecessary but handles an Android/iOS edge case where secure storage persists after uninstall. Don't remove it.
- Use package imports (`import 'package:frosty/...'`), not relative imports
- Always include trailing commas
- Use single quotes
- Run `flutter analyze` after making changes. Run `flutter test` if changes touch testable logic.
