@islom9797 Hi, have you happen to make this work? I'm also facing the same issue

[muneebahmad0600]

@Larpoux @RitchieP @islom9797 Having same issue. ` void startRecorder() async { if (_mRecorder!.recorderState == RecorderState.isPaused) { resumeRecorder(); return; } Directory tempDir = await getApplicationDocumentsDirectory(); _mRecorder! .startRecorder( toFile: '${tempDir.path}/audio.wav', codec: Codec.pcm16WAV, audioSource: theSource, ) .then((value) { setState(() { _isRecording = true; context.read().toggleTimer(); }); }); }

void stopRecorder() async { await _mRecorder!.stopRecorder().then((value) { context.read().pauseTimer(); setState(() { _recordingPath = value.toString(); _isRecording = false; Timer(const Duration(milliseconds: 500), () { NavigationService.pushReplacement( UploadRecordingScreen(recordingPath: _recordingPath), ); }); }); }); }`

value is empty string when recording is stopped. @sofakeer please reply if you can help

Actually, I know that there is a bug in Flutter Sound when the App tries to use the File Path returned by stopRecorder().

This is perhaps the reason for your issue. I will work on that point tomorrow. Sorry for the bug.

It's been quite a while since I worked on my project that required voice recording. I managed to make it work towards the end but I forgot what was the exact issue.

But I can share the link to my source code if you'd like to have a look.

I am currently in the process of releasing a new flutter sound version with a bug fixed on Android with PCM16-WAV. The new version will be accessible in half an hour. I think that it will solve your issue.

Flutter Sound 9.16.1 is released :

9.16.1

• Fix a bug on Android. The recorded file path was incorrect during StopRecorder() with codec=WAV-PCM16. (973).
