Flutter: Music plays after closing application

Question

I want to make a music player by flutter. I want to, when user play a music and close the application, The music is playing in the background as a service.

I googled and i found out,with these flutter libraries, not possible to do (means music player work as a background service) ? Is it true?

Or is there any way to do that?

Answer 1

To stop the music when the app is in the background, you need to bind the Audio Player to the WidgetsBindingObserver to listen to the app lifecycle state changes.

create a custom class for example

 class _Handler extends WidgetsBindingObserver {
    @override
    void didChangeAppLifecycleState(AppLifecycleState state) {
      if (state == AppLifecycleState.resumed) {
         AudioPlayer.resume(); // Audio player is a custom class with resume and pause static methods
       } else {
         AudioPlayer.pause();
       }
     }
  }

and then inside your main.dart you can you use it as bellow:

main() async {
   WidgetsFlutterBinding.ensureInitialized();

   runApp(YourApp());

    WidgetsBinding.instance.addObserver(new _Handler());
  }
