This is the Exception I got

Answer 1

As explained in the exception message: "Player is not open"

Flutter_sound documentation say:

2. Open and close the audio session

Before calling startPlayer() you must open the Session.

When you have finished with it, you must close the session. A good places to put those verbs are in the procedures initState() and dispose().

@override
  void initState() {
    super.initState();
    // Be careful : openAudioSession return a Future.
    // Do not access your FlutterSoundPlayer or FlutterSoundRecorder before the completion of the Future
    _myPlayer.openAudioSession().then((value) {
      setState(() {
        _mPlayerIsInited = true;
      });
    });
  }



  @override
  void dispose() {
    // Be careful : you must `close` the audio session when you have finished with it.
    _myPlayer.closeAudioSession();
    _myPlayer = null;
    super.dispose();
  }
