Description
Package version
record 6.1.0

Flutter 3.35.1
Dart 3.9.0
Environment
- OS: fedora 42
Describe the bug
When stopping a recording, I get the following error:
Bad state: StreamSink is bound to a stream
I'm using the default configuration.
To Reproduce
RecorderService:
class AudioRecorderService {
final AudioRecorder _audioRecorder = AudioRecorder();
final Logger _logger = Logger('AudioRecorderService');
String? recordingPath;
bool isRecording = false;
Future<void> startRecording(String fileName) async {
try {
if (await hasPermission()) {
final directory = await getApplicationDocumentsDirectory();
final path = '${directory.path}/$fileName';
_logger.info('Starting recording to path: $path');
await _audioRecorder.start(const RecordConfig(), path: path);
isRecording = true;
recordingPath = null;
_logger.info('Started recording to $path');
} else {
_logger.warning('Permission to record audio denied.');
}
} catch (e) {
_logger.severe('Error starting recording: $e');
}
}
Future<void> stopRecording() async {
try {
final path = await _audioRecorder.stop();
_logger.info('Stopped recording. File saved at: $path');
_audioRecorder.dispose();
recordingPath = path;
isRecording = false;
} catch (e) {
_logger.severe('Error stopping recording: $e');
}
}
}
Expected behavior
The recording should be stopped, once the stopRecording method is invoked.
