Riverpod — Scoping providers
Instructions
Scoping means changing a provider's behavior for only part of the app by overriding it in a non-root ProviderScope. Use cases: page-specific customization (e.g. theme for one page), performance (e.g. rebuild only the item that changed in a ListView), or avoiding passing family parameters through the tree.
Note: Scoping is complex and may be reworked in future Riverpod versions. Use with care.
Opt-in: dependencies
By default you cannot scope a provider. Opt in by setting dependencies on the provider. The first scoped provider usually has dependencies: const [].
final currentItemIdProvider = Provider<String?>(
dependencies: const [],
(ref) => null,
);

riverpod-codegen-and-hooks
Use Riverpod code generation (@riverpod, riverpod_generator) and hooks (hooks_riverpod, HookConsumerWidget, flutter_hooks with Riverpod). Use when the user asks about @riverpod, code generation, riverpod_generator, when to use codegen, or using flutter_hooks with Riverpod (HookConsumerWidget, HookConsumer).
30riverpod-providers
Declare and use Riverpod providers (Provider, FutureProvider, StreamProvider, NotifierProvider, AsyncNotifierProvider, StreamNotifierProvider); unmodifiable vs modifiable, top-level declaration, Ref, Notifier build method. Use when creating providers, choosing provider type, writing Notifier classes, or understanding Riverpod state. Use this skill whenever the user asks about Riverpod providers, provider types, or notifiers.
29riverpod-consumers
Use Riverpod Consumer, ConsumerWidget, and ConsumerStatefulWidget to read and watch providers in widgets; WidgetRef, builder ref parameter. Use when building widgets that need to access Riverpod providers, ref.watch or ref.read in the UI, or converting StatelessWidget to ConsumerWidget. Prefer this skill when the user asks how to use providers in Flutter widgets or why ConsumerWidget is required.
24riverpod-getting-started
Install Riverpod (flutter_riverpod or riverpod), wrap the app in ProviderScope, run a hello-world provider, and optionally enable riverpod_lint and code generation. Use when starting a Flutter or Dart project with Riverpod, adding the Riverpod dependency, or setting up ProviderScope and a first provider. For version highlights see the official Riverpod docs.
23riverpod-auto-dispose
Enable automatic disposal of Riverpod providers when they have no listeners; keepAlive, onDispose, invalidate, ref.keepAlive. Use when preventing memory leaks, caching only while used, or cleaning up resources when a provider is no longer needed. Use this skill when the user asks about auto-dispose, keepAlive, or when to dispose Riverpod state.
21riverpod-observers
Use ProviderObserver to log or debug Riverpod provider lifecycle; didUpdateProvider, ProviderScope observers, naming providers. Use when adding logging, analytics, or debugging for provider state changes. Use this skill when the user asks about ProviderObserver, logging Riverpod, or debugging provider updates.
