Riverpod — Automatic disposal

Instructions

With automatic disposal enabled, Riverpod destroys a provider's state when it has no listeners for one frame. This frees memory and stops work (e.g. network requests) when the provider is no longer used.

Enabling

• Code generation: Enabled by default. Disable with @Riverpod(keepAlive: true).
• Manual: Add isAutoDispose: true when creating the provider (e.g. Provider.autoDispose(...) or FutureProvider.autoDispose(...)).

// Codegen: disable auto-dispose
@Riverpod(keepAlive: true)
String helloWorld(Ref ref) => 'Hello world!';
