InheritedProvider<T> class

A generic implementation of an InheritedWidget.

Any descendant of this widget can obtain value using Provider.of.

Do not use this class directly unless you are creating a custom "Provider". Instead use Provider class, which wraps InheritedProvider.

• DeferredInheritedProvider, a variant of this object where the provided object and the created object are two different entity.

Constructors

InheritedProvider({Key? key, Create<T>? create, T update(BuildContext context, T? value)?, UpdateShouldNotify<T>? updateShouldNotify, void debugCheckInvalidValueType(T value)?, StartListening<T>? startListening, Dispose<T>? dispose, TransitionBuilder? builder, bool? lazy, Widget? child})

Creates a value, then expose it to its descendants.

InheritedProvider.value({Key? key, required T value, UpdateShouldNotify<T>? updateShouldNotify, StartListening<T>? startListening, bool? lazy, TransitionBuilder? builder, Widget? child})

Expose to its descendants an existing value,
