flutter - Flutter Awesome Notification couldn't bind a method to action button

Question

I'm developing an app which needs to answer the notifications. I can display the button when I received the notification. However, I couldn't bind any method to it. Here is my code:

Future<void> firebaseMessagingBackgroundHandler(RemoteMessage message)  async {
  await Firebase.initializeApp();
    AwesomeNotifications().createNotification(
          content: NotificationContent(
              id: 10,
              channelKey: 'basic_channel',
              title: 'Simple Notification',
              body: 'Simple body'),
          actionButtons: [
            NotificationActionButton(
                label: 'TEST',
                enabled: true,
                buttonType: ActionButtonType.Default,
                key: 'test',
                )
          ]);
    print("Background message service");
  }

Thank you for your helps!

You should create a event stream and listen to events like that:

    AwesomeNotifications().actionStream.listen((event) {
      print('event received!');
      print(event.toMap().toString());
      // do something based on event...
    });
