Topic	Reference	Load When
Riverpod	`references/riverpod-state.md`	State management, providers, notifiers
Bloc	`references/bloc-state.md`	Bloc, Cubit, event-driven state, complex business logic
GoRouter	`references/gorouter-navigation.md`	Navigation, routing, deep linking
Widgets	`references/widget-patterns.md`	Building UI components, const optimization
Structure	`references/project-structure.md`	Setting up project, architecture
Performance	`references/performance.md`	Optimization, profiling, jank fixes

Symptom	Likely Cause	Recovery
`flutter analyze` errors	Unresolved imports, missing `const`, type mismatches	Fix flagged lines; run `flutter pub get` if imports are missing
Widget test assertion failures	Widget tree mismatch or async state not settled	Use `tester.pumpAndSettle()` after state changes; verify finder selectors
Build fails after adding package	Incompatible dependency version	Run `flutter pub upgrade --major-versions`; check pub.dev compatibility
Jank / dropped frames	Expensive `build()` calls, uncached widgets, heavy main-thread work	Use `RepaintBoundary`, move heavy work to `compute()`, add `const`
Hot reload not reflecting changes	State held in `Notifier` not reset	Use hot restart (`R` in terminal) to reset full app state
