Use the Flutter team's recommended app architecture
Enforces feature state as one Notifier/AsyncNotifier/StreamNotifier ViewModel over an immutable state value with value equality, private mutable state mutated only through intent methods, derive-don't-store, a single write path through a repository, and unidirectional data flow; Riverpod 3.x is DI (providers-as-collaborators, ProviderScope overrides per flavor, throwing seams), reads split ref.watch/.select for display vs ref.read(p.notifier) in callbacks vs ref.listen for side effects, async modeled as AsyncValue, per-entity state family-keyed + autoDispose, and stale-closure captures / legacy StateProvider-StateNotifierProvider-ChangeNotifierProvider / get_it / package:provider are banned. Use when adding state to a screen, writing a feature controller/ViewModel, wiring providers or DI, deriving a read model from a stream, or reviewing rebuild/state-leak/disposal/write-path issues.
