BlocNotificationListener<B extends BlocNotificationMixin<S, N>, S, N> class

The BlocNotificationListener is a widget that listens for notifications from a BlocBase that uses the BlocNotificationMixin, and passes them to a callback provided by the user. This widget is similar to the BlocListener widget, but is specialized for handling notifications that are not tied to the state.

To use the BlocNotificationListener, simply create an instance of the widget and provide a callback to handle the notifications. You can also provide an optional BlocWidgetListener to handle state changes, a BlocListenerCondition to conditionally listen to state changes, and a child widget to render below the BlocNotificationListener.

BlocNotificationListener<MyBloc, MyState, MyNotification>(
  notificationListener: (context, notification) {
    // Handle the notification
 },
);
