Describe the bug
I'm trying to record audio and download it to my computer. When I hit stop, the recorded audio size is always 64 bytes and the file size is 1KB, but nothing is being recorded.

 Future<void> startAudio({required BuildContext context}) async {
    try {
      _isRecording = true;
      notifyListeners();
      await record.start(
          const RecordConfig(
            encoder: AudioEncoder.pcm16bits,
            sampleRate: 22000,
            numChannels: 2,
            bitRate: 128000,
            autoGain: true,
            echoCancel: true,
            noiseSuppress: true
          ),
          path: "");
    } catch (e) {
      print(e);
    }
  }
  
  
   Future<void> stopRecordingAndSave() async {
    try {
      var audioData = await record.stop();
      _isRecording = false;
      notifyListeners();

      if (audioData != null) {
        print("Audio data size: ${audioData.length} bytes");

        final blob = html.Blob([audioData], 'audio/wav');
        final url = html.Url.createObjectUrlFromBlob(blob);

        final anchor = html.AnchorElement(href: url)
          ..setAttribute("download", "recording.wav")
          ..click();

        html.Url.revokeObjectUrl(url);
      } else {
        print("No audio data available.");
      }
    } catch (e) {
      print("Error stopping and saving");
    }
    notifyListeners();
  }

What you call audiodata is your path (blob URL in web). You can remove all your code below its initialisation.
By the way, PCM is not strictly WAV format.
