DeferredInheritedProvider<T, R> class

An InheritedProvider where the object listened is not the object emitted.

For example, for a stream provider, we'll want to listen to Stream<T>, but expose T not the Stream.

  • InheritedProvider, a variant of this object where the provider object and the created object are the same.

Constructors

DeferredInheritedProvider({Key? key, required Create<T> create, Dispose<T>? dispose, required DeferredStartListening<T, R> startListening, UpdateShouldNotify<R>? updateShouldNotify, bool? lazy, TransitionBuilder? builder, Widget? child})
Lazily create an object automatically disposed when DeferredInheritedProvider is removed from the tree.
DeferredInheritedProvider.value({Key? key, required T value, required DeferredStartListening<T, R> startListening, UpdateShouldNotify<R>? updateShouldNotify, bool? lazy, TransitionBuilder? builder, Widget? child})
Listens to value and expose its content to child and its descendants.
