    Try to read for an answer here: How to get a Uint8List from a Network image by url in Flutter?

    You have a binary object that you have url to. Just download it and store it as UIntList.

    if (kIsWeb) {
  final blobFilePath = html.window.sessionStorage[audioFilePath];
  if (blobFilePath != null) {
    final uri = Uri.parse(blobFilePath);
    final client = http.Client();
    final request = await client.get(uri);
    final bytes = await request.bodyBytes;
    print('response bytes.length: ${bytes.length}');
  }
}

    audioFilePath is the blob url actually, can be found in startPlayer method in demo.dart file for example.

    Hope this helps.
