RuntimeException on stop

[ghost]

If you quickly start and stop a recording, a RuntimeException is thrown from Java, resulting in a PlatformException in Flutter:

You should be able to reproduce this issue with the following snippet:

import 'package:path/path.dart';
import 'package:path_provider/path_provider.dart';
import 'package:permission_handler/permission_handler.dart';
import 'package:uuid/uuid.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Foo(),
    );
  }
}

class Foo extends StatelessWidget {
  static final _uuid = Uuid();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton(
          child: Text('Quickly start and stop recording'),
          onPressed: quicklyStartAndStopRecording,
        ),
      ),
    );
  }

  Future<void> quicklyStartAndStopRecording() async {
    await PermissionHandler().requestPermissions([PermissionGroup.microphone]);

    final directory = await getTemporaryDirectory();
    final path = join(directory.path, '${_uuid.v4()}.m4a');

    await AudioRecorder.start(
      path: path,
      audioOutputFormat: AudioOutputFormat.AAC,
    );

    await Future.delayed(
      const Duration(milliseconds: 100),
      AudioRecorder.stop,
    );
  }
}

To make matters worse, you cannot stop the recording after is error was thrown. Also, await AudioRecorder.isRecording stays returning true.

If you try to call AudioRecorder.stop() again:

[sayhicoelho]

it seems it is a bug. here facing with the same issue!

[huangruiLearn]

may cause by stop() is called immediately after start()... i tried `` try {
mRecorder.stop();
mRecorder.reset();
mRecorder.release();
mRecorder = null;
}catch (RuntimeException e){

}` ``
Is there a better way?
