To Reproduce
Unfortunately it never happened during the debug neither of the internal testing of the app so i have no clue on how to reproduce it...

Hi @Tom3652, Thanks for filling the issue.

Can you please send me reproducible steps or audio files? Also, please share your flutter—v console output.

@jay-simformsolutions

Hey @jay-simformsolutions

Thanks for the quick reply, however as i said it happens on my live app and on Android devices, i have no ways to reproduce it unfortunately 😐

I was hoping you would know what is the "reply already submitted" error...

I am adding the Redmi Note 12 5G under Android 12 as a new phone crashing today.

@Tom3652

@Tom3652, We will investigate this issue and try to solve it as soon as possible.

Hello @Tom3652, I just want to know if you are using the stopAllPlayer method in your app to stop all active players together.

Hello both of you, thank you very much for your interest and answers.

I am actually not using stopAllPlayers, please see all the different methods i am calling together :

  final PlayerController controller = PlayerController();

  try {
      await controller.preparePlayer(path: audioFile);
      controller.setFinishMode(finishMode: FinishMode.stop);
      await controller.startPlayer();
    } catch (e) {
     print("error playing audio file : $e");
    }
    
  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

In Another class :

  final PlayerController controller = PlayerController();
  StreamSubscription<PlayerState>? playerStateSubscription;
  AnimationController? playAnimator;
  
   double waveWidth = 0;
   String filePath = "value";

  Future<void> init() async {
    waveWidth = widget.width - 60;

    if (mounted) {
    
        playAnimator = AnimationController(
        vsync: this, duration: const Duration(milliseconds: 250));

      print("File path : $filePath");
      await controller.preparePlayer(
          path: filePath,
          shouldExtractWaveform: true,
          noOfSamples: _playerWaveStyle.getSamplesForWidth(waveWidth));

      playerStateSubscription = controller.onPlayerStateChanged.listen((state) {
        if (mounted) {
          stateNotifier.value = state;
          if (state == PlayerState.paused && mounted) {
            playAnimator?.reverse();
          }
        }
      });

      durationListener = controller.onCurrentDurationChanged.listen((millis) {
        positionNotifier.value =
            getAudioDuration(Duration(milliseconds: millis));
      });

      int waiting = Platform.isAndroid ? 1000 : 0;
      // On Android
      Future.delayed(Duration(milliseconds: waiting)).then((value) async {
        int millis = await controller.getDuration(DurationType.max);

        positionNotifier.value =
            getAudioDuration(Duration(milliseconds: millis));
        print(
            "Duration for file $filePath : ${positionNotifier.value}");
      });

      stopListener = AudioPlayerManager.instance.onStopPlayerListener.stream
          .listen((audioFile) async {
        if (controller.playerState.isPaused && mounted) {
          playAnimator?.reverse();
        }
        if (audioFile != filePath &&
            (controller.playerState.isPlaying ||
                controller.playerState.isPaused) &&
            mounted) {
          await controller.pausePlayer();
        }
      });
      if (mounted) {
        setState(() {});
      }
    }
  }

  @override
  void initState() {
    init();
    super.initState();
  }

  @override
  void dispose() {
    controller.dispose();
    playerStateSubscription?.cancel();
    durationListener?.cancel();
    stopListener?.cancel();
    playAnimator?.dispose();
    super.dispose();
  }

 Future<void> onTap() async {
    if (filePath.isNotEmpty) {
      HapticFeedback.mediumImpact();
      controller.playerState.isPlaying ? pause() : play();
    }
  }

  Future<void> pause() async {
    await controller.pausePlayer();
    playAnimator!.reverse();
  }

  Future<void> play() async {
    AudioPlayerManager.instance.onStopPlayerListener.add(filePath);
    controller.setFinishMode(finishMode: FinishMode.pause);
    await controller.startPlayer();
    playAnimator!.forward();
  }

Now i wonder if the error is to not await the controller.setFinishMode(finishMode: FinishMode.pause); call before startPlayer and / or the order of disposing objects ?

Thanks a lot for your help

Hi both of you, i have got a new crash today that is on the preparePlayer. This is a variant of this bug probably :

@Tom3652

@Tom3652, Thanks for providing the information. We are working on this issue and will update you once we find a solution.

@jay-simformsolutions

Hi @jay-simformsolutions thank you very much i really apreciate it.

I simply add the proportion here :

24 crashes for com.simform.audio_waveforms.WaveformExtractor$startDecode$1$1.onError(WaveformExtractor.kt:109)
8 crashes for com.simform.audio_waveforms.AudioPlayer$preparePlayer$2.onPlayerError(AudioPlayer.kt:48)

And so far no other methods are revealing this issue 🙏 and no crashes at all on iOS !

Note : i don't add the new impacted phones since it's probably not device-specific / android-version-specific, but if i will provide all the info i can give if you need it of course

Crashes are growing, i know this was a holiday time recently and i wish you all a happy new year !
Do you have any ETA for a fix of that investigation ?

It is still the case using flutter: 3.27.1 and the first crash i have received is using 3.24.x

Are there any updates on this issue?

Facing the same issue, any update on this issue ?

From the latest release of Flutter 3.27.3 it seems the crash is simply gone, but other people here may correct me if i am wrong !
I am still having a lot of #376 however

Thanks for the info. Will try upgrading my Flutter to 3.27.3

I will release an app version with flutter 3.29.0 next week will see if this crash is happening again.
So far so good with 3.27.3

I have spoken a bit too fast unfortunately, it drastically lowered the crash rate but they are still present unfortunately in 3.27.3

I have no more this crash using 3.29.3 version of flutter
