Implementation

Future<void> start(String url, {String? to}) async {
  progress.value = 0;
  status.value = DownloadStatus.inProgress;
  _completer = Completer<File?>();

  try {
    file = await PlatformUtils.download(
      url,
      filename,
      size,
      path: to,
      checksum: checksum,
      onReceiveProgress: (count, total) => progress.value = count / total,
      cancelToken: _token,
    );
    _completer?.complete(file);

    if (file != null) {
      status.value = DownloadStatus.isFinished;
      onDownloaded?.call(file!);
    } else {
      status.value = DownloadStatus.notStarted;
    }
  } catch (e) {
    _completer?.completeError(e);
    status.value = DownloadStatus.notStarted;
