watch<T extends Bloc> static method
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
static T watch<T extends Bloc>(BuildContext context) =>
context.watch<BlocNotifier<T>>().bloc;
