TrackDefault 构造函数

实现

factory TrackDefault(
    String type, String language, String label, List<String> kinds,
    [String? byteStreamTrackID]) {
  if (byteStreamTrackID != null) {
    List kinds_1 = convertDartToNative_StringArray(kinds);
    return TrackDefault._create_1(
        type, language, label, kinds_1, byteStreamTrackID);
  }
  List kinds_1 = convertDartToNative_StringArray(kinds);
  return TrackDefault._create_2(type, language, label, kinds_1);
}
