Start download from the beginning

for example :

My file size is 100 MB. When I start the download, it proceeds to 50% completion. However, if my network connection is interrupted at that point, the download restarts from the beginning once the network is restored. Ideally, the download should resume from where it left off.

this is my code :

void downloadConfig() {

FileDownloader().configure(
  globalConfig: [
    (Config.requestTimeout, const Duration(seconds: 100)),
  ],
  androidConfig: [(Config.runInForegroundIfFileLargerThan, 200)],
  iOSConfig: [
    (Config.localize, {'Cancel': 'StopIt'}),
  ],
);

}

void downloadNotificationSetup() {

FileDownloader()
    .configureNotificationForGroup(
      FileDownloader.defaultGroup,
      running: const TaskNotification('Download running',
          'Video - {progress} - speed {networkSpeed} and {timeRemaining} remaining'),
      complete:
          const TaskNotification('Download complete', 'Download complete'),
      error: const TaskNotification('Download error', 'Download failed'),
      paused: const TaskNotification(
          'Download pause', 'Paused with metadata {metadata}'),
      progressBar: true,
      tapOpensFile: false,
    )
    .configureNotification(
      complete: const TaskNotification(
          'Download {filename}', 'Download complete'),
      tapOpensFile: false,
      progressBar: true,
    );

}

Future downloadSingleVideo( {required String url, required String fileName, required int fileSize}) async { double fileSizeInMB = fileSize / (1024 * 1024); try {

  final task = DownloadTask(
      url: url,
      filename: "$fileName.mp4",
      baseDirectory: BaseDirectory.root,
      directory: controller.haveSDCard
          ? controller.sdCardPath
          : controller.localStoragePath,
      updates: Updates.statusAndProgress,
      allowPause: true,
      retries: 5,
      taskId: fileName);

  final successfullyEnqueued = await FileDownloader().enqueue(
    task,
  );
  if (successfullyEnqueued) {
    controller.onGoingAllDownloadingFileSize += fileSizeInMB;
    controller.taskMapping[task.taskId] =
        VideoFile(fileName: fileName, fileSize: fileSizeInMB);
  } else {
    showMassage("Download failed to start.", isSuccess: false);
  }
} catch (err) {
  showApiErrorMessage(err);
}

}
