@MajedDH I get the following error when I try to call Bringtoforeground.bringAppToForeground();

I call the function from my cloud messaging background handler

  static Future<dynamic> myBackgroundMessageHandler(Map<String, dynamic> message) async {
    print('on background message');
      Bringtoforeground.bringAppToForeground();
  }

Firebase has a problem with background message handler See here: #1878

It's not been solved yet.

In that case I had to fork the fireflutter plugin and override onMessageRecieved, take a look at this file: CustomFlutterFirebaseMessagingService.java

Currently facing the same issue, couldn't deduce the source, had to start the project from scratch
