FutureProvider<T> class

Listens to a Future and exposes its result to child and its descendants.

It is considered an error to pass a future that can emit errors without providing a catchError method.

updateShouldNotify can optionally be passed to avoid unnecessarily rebuilding dependents when Provider is rebuilt but value did not change.

Defaults to (previous, next) => previous != next. See InheritedComponent.updateShouldNotify for more information.

Constructors

FutureProvider({Key? key, required Create<Future<T>?> create, required T initialData, ErrorBuilder<T>? catchError, UpdateShouldNotify<T>? updateShouldNotify, bool? lazy, TransitionBuilder? builder, Component? child}): Creates a Future from create and subscribes to it.
FutureProvider.value({Key? key, required Future<T>? value, required T initialData, ErrorBuilder<T>? catchError, UpdateShouldNotify<T>? updateShouldNotify, TransitionBuilder? builder, Component? child}): Listens to value and expose it to all of FutureProvider descendants.
