Sorry for the late reply :(

The return value is considered to be the piano key with the closest probability value to white noise.

You could use the following APIs appropriately to distinguish closer piano keys.

Map<String, String> getNotesDetail(List<dynamic> event) {
    Map<String, String> result = Map();
    event.forEach((element) {
      result['key'] = getNoteName(element["key"]);
      result['frame'] = element["frame"].toString();
      result['onset'] = element["onset"].toString();
      result['offset'] = element["offset"].toString();
      result['velocity'] = element["velocity"].toString();
    });
    return result;
  }
