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.
