Platforms you faced the error (IOS or Android or both?)

Android

Expected behavior

Report the playback data to start a listener and observe the changes.

[Flutter Sound - Start Player] Player resumed
I/flutter (22476):  duration: 1, currentPosition: 0.203
I/flutter (22476):  duration: 1, currentPosition: 0.389
I/flutter (22476):  duration: 1, currentPosition: 0.541
I/flutter (22476):  duration: 1, currentPosition: 0.812
D/FlutterSoundPlugin(22476): Plays completed.

Actual behavior

On Android I am not receiving the data in the PlayStatus Stream listener, due to this I cannot verify the maximum and current audio time and whether it has finished.

[Flutter Sound - Start Player] Player resumed
D/FlutterSoundPlugin(22476): Plays completed.

Tested environment (Emulator? Real Device?)

Both (Emulator and Xiaomi Note 8)

Steps to reproduce the behavior

I’m using Flutter Sound in conjunction with Flutter Bloc.

The methods that correspond to the events are as follows:

• First the download is performed:

  Stream<ChatState> _mapDownloadAudio(DownloadAudioChatEvent event) async* {
    Directory dir = await getTemporaryDirectory();
    String pathFile = '${dir.path}/${event.audio.fileName}.aac';
    String bucket =
        '${event.audio.path}/${detailsTalk.idTalk}/${event.audio.fileName}';
    File checkFile = File(pathFile);
    if (!await checkFile.exists()) {
      var response = await awsGet.getObject(bucket, pathFile);
      if (response.statusCode >= 200) {
        event.audio.file = File(pathFile);
        _updateAudioData(event.audio);
      }
    } else {
      event.audio.file = checkFile;
      _updateAudioData(event.audio);
    }
    yield DownloadedAudioChatState(conversations, event.audio);
  }

• After the download, you can start the audio:

  Stream<ChatState> _mapEventPlayAudio(PlayAudioChatEvent event) async* {
    if (_sound != null && playerIsPlaying()) {
        await player.stopPlayer();
        _canceledPlayer(_sound);
        _updateAudioData(_sound);
        yield StopAudioChatState(conversations, _sound);
    }
    await _startPlayer(event.audio);
    _updateAudioData(event.audio);
    yield PlayAudioChatState(conversations, event.audio);
  }

  Future<void> _startPlayer(ExtraData audio) async {
    try {
      player.startPlayer(audio.file.path).then((message) {
        log(message, name: 'Flutter - Start Player');
        _onPlay = player.onPlayerStateChanged
            .listen((status) => listeningStatus(status));
      });
      audio.isPlaying = true;
      _sound = audio;
    } catch (e) {
      log(e.toString(), name: 'Flutter Sound - Error');
    }
  }

  void listeningStatus(PlayStatus status) {
    log(status.toString(), name: 'Player - PlayStatus');
    if (status != null) {
      _sound.timeStatus = status;
      add(UpdatePlayStatusChatEvent(_sound));
    } else {
      add(PauseAudioChatEvent(_sound));
    }
  }

bool playerIsPlaying() => player.audioState == t_AUDIO_STATE.IS_PLAYING;

@Josue10599 ,

Yes, I confirm that Flutter Sound and FCM are not good friends together. I tried to run the Flutter Sound Example with a special APP linked with Firebase Messaging, and it does not work. Android Media Player is really painful (I have many problems in Flutter Sound not correctly solved because of Android Media Player). I think it is time, now, to consider rewriting the Flutter Sound Recorder using other native tools. Just be patient … time is the bottle neck.
