  }

  @override
  Future<UpdateInfo> checkUpdate() async {

    return Future.value(0);
  }

  @override
  Future<int> install() {
    // Perform install package
    return Future.value(0);
  }

  @override
  Future<Stream<int>> startDownload() {
    // Perform download, resolve a stream for progress notification
    // When progress > 100(e.g. 101), the modal mark state to readyToInstall
    return Future.value(Stream.fromFutures([
      Future.delayed(Duration(milliseconds: 150 * 1), () => 20),

      Future.delayed(Duration(milliseconds: 150 * 3), () => 60),
      Future.delayed(Duration(milliseconds: 150 * 4), () => 80),
      Future.delayed(Duration(milliseconds: 150 * 5), () => 100),
