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 InheritedWidget.updateShouldNotify for more information.
