StreamNotifierProvider<NotifierT extends StreamNotifier<ValueT>, ValueT> class final Providers

A provider which creates and listen to an StreamNotifier.

This is similar to FutureProvider but allows to perform side-effects.

The syntax for using this provider is slightly different from the others in that the provider's function doesn't receive a "ref" (and in case of family, doesn't receive an argument either). Instead the ref (and argument) are directly accessible in the associated StreamNotifier.

Constructors

StreamNotifierProvider.new(NotifierT _createNotifier(), {String? name, Iterable<ProviderOrFamily>? dependencies, bool isAutoDispose = false, Retry? retry})
A provider which creates and listen to an StreamNotifier.

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
overrideWith(NotifierT create()) → Override
Override the provider with a new initialization function.
inherited
overrideWithBuild(RunNotifierBuild<NotifierT, Stream<ValueT>> build) → Override
Overrides the build method of a notifier, allowing you to replace the default implementation with a custom one for testing or specific use cases.
inherited
selectAsync<OutT>(OutT selector(ValueT data)) → ProviderListenable<Future<OutT>>
A variant of select for asynchronous values
inherited
toString() String
A string representation of this object.

Constants

autoDispose → const AutoDisposeStreamNotifierProviderBuilder
Marks the provider as automatically disposed when no longer listened to.
family → const StreamNotifierProviderFamilyBuilder
A group of providers that builds their value from an external parameter.
