watchBloc<T extends Bloc> method

T watchBloc<T extends Bloc>()

Similar to the WatchContext.watch method from the Provider package.

Blocs normally won't automatically redraw the Widget that calls them, unless you specifically watch the BlocNotifier. This is a helper function to remove the boilerplate of retrieving the BlocNotifier and unwrapping it.

Implementation

T watchBloc<T extends Bloc>() => BlocProvider.watch<T>(this);
