Triggering actions within the app with 1.1.x about pushy-flutter

[pushy]

Hi @calvinmuller-wi,
That's a great question, thanks for reaching out.

We recommend creating a top-level variable to hold a reference to your State<> class context, which can be accessed inside the backgroundNotificationListener, to pass notifications to your Widget context as follows:

1. Add a top-level variable to your lib/main.dart, replacing _PushyDemoState with your own State<> class name:

_PushyDemoState currentState;

2. Add this code in the void initState() {} method of your State class implementation:

@override
void initState() {
    super.initState();
    
    // Start the Pushy service
    Pushy.listen();

    // Pass reference to State context
    currentState = this;
}

3. Add a new method in your State<> class to process notifications in foreground:

  void onNewNotification(Map<String, dynamic> data) {
      // ....
  }

4. Access the state in backgroundNotificationsListener (will be null if it's running in the background) and invoke your method:

void backgroundNotificationListener(Map<String, dynamic> data) {
    // Print notification payload data
    print('Received notification: $data');


   // If app is in foreground, pass notification to Widget
   if (currentState != null) {
       currentState.onNewNotification(data);
   }

    // .......
}
