Add your record configuration RecordConfig(...)

const RecordConfig(
    encoder: AudioEncoder.pcm16bits,
    sampleRate: 16000,
    numChannels: 1,
  );

To Reproduce

Call recorder like this

final recorderStream = await _recorder.startStream(_recorderConfig);

When I stop the recorder (eg: VAD silent signal) like this

await _recorder.stop();

It crashes only on Android, iOS is working fine

Expected behavior

It should not crash on Android

I can't reproduce it with the example project. Can you provide a reproducer?

[llfbandit]

Version 5.1.1 has been released. It may worth a try. Feedback welcomed!

[Roee-Tsur]

Didn't try upgrading the package but for me this happens when stop was called twice and together.

@llfbandit - This issue is reproducible on Android devices with v5.1.1

It can be reproduced by calling start and stop in quick succession [recordings of 1s]. It generally crashes while stopping the 3rd or 4th recording.
