startRecording() async {
  bool recordPermission = await _requestPermission();
  if (recordPermission) {
    await _nextAudioRecorder.startRecorder('output.mp4');
    await _nextAudioRecorder.setSubscriptionDuration(_subscriptionDuration);
    _nextAudioRecorder.startRecorderSubscriptions((e) async {
      // You can use this to trigger function or listen for special tasks like detecting when the user stops talking.
    });
  } else {
    if (kDebugMode) {
      print('Audio permission is required.');
    }

  if (outputFilePath != null) {
    if (kDebugMode) {
      print('[StartRecordEvent] Output recorded FilePath: $outputFilePath');
