ALDownloader.download(url,
    downloaderHandlerInterface:
        ALDownloaderHandlerInterface(progressHandler: (progress) {
      debugPrint(
          "ALDownloader | downloading, the url = $url, progress = $progress");
    }, successHandler: () {
      debugPrint("ALDownloader | download successfully, the url = $url");
    }, failureHandler: () {
      debugPrint("ALDownloader | download failed, the url = $url");
    }, pausedHandler: () {
      debugPrint("ALDownloader | download paused, the url = $url");
    }));

/// add a download handle interface
ALDownloader.addALDownloaderHandlerInterface(
    ALDownloaderHandlerInterface(progressHandler: (progress) {
      debugPrint(
              "ALDownloader | downloading, the url = $url, progress = $progress");
    }, successHandler: () {
      debugPrint("ALDownloader | download successfully, the url = $url");
    }, failureHandler: () {
      debugPrint("ALDownloader | download failed, the url = $url");
    }, pausedHandler: () {
      debugPrint("ALDownloader | download paused, the url = $url");
    }),
    url);

/// remove a download handle interface
ALDownloader.removeALDownloaderHandlerInterfaceForUrl(url);
ALDownloader.removeALDownloaderHandlerInterfaceForAll;

/// get the download status of [url]
ALDownloaderStatus status = ALDownloader.getDownloadStatusForUrl(url);

/// cancel
///
/// for details, see interface description
ALDownloader.cancel(url);
ALDownloader.cancelAll;

/// pause
///
/// for details, see interface description
ALDownloader.pause(url);
ALDownloader.pauseAll;

/// remove
///
/// for details, see interface description
ALDownloader.remove(url);
ALDownloader.removeAll;

ALDownloaderBatcher

/// batch downlaod
ALDownloaderBatcher.downloadUrls(kTestVideos,
    downloaderHandlerInterface:
        ALDownloaderHandlerInterface(progressHandler: (progress) {
      debugPrint("ALDownloader | downloading, progress = $progress");
    }, successHandler: () {
      debugPrint("ALDownloader | download successfully");
    }, failureHandler: () {
      debugPrint("ALDownloader | download failed");
    }, pausedHandler: () {
      debugPrint("ALDownloader | download paused");
    }));

/// summarize the download status of a set of urls
final status = ALDownloader.getDownloadStatusForUrls(urls);

ALDownloaderPersistentFileManager - disk path management by url

final model = await ALDownloaderPersistentFileManager

debugPrint(
    "ALDownloader | get 'directory path' by [url], url = $url, path = $path2\n");

final path3 = await ALDownloaderPersistentFileManager
    .getAbsoluteVirtualPathOfFileWithUrl(url);
debugPrint(
    "ALDownloader | get 'virtual file path' by [url], url = $url, path = $path3\n");

final path4 = await ALDownloaderPersistentFileManager
    .getAbsolutePhysicalPathOfFileWithUrl(url);
debugPrint(
    "ALDownloader | get 'physical file path' by [url], url = $url, path = $path4\n");

final isExist = await ALDownloaderPersistentFileManager
    .isExistAbsolutePhysicalPathOfFileForUrl(url);

    "ALDownloader | check whether [url] corresponds to physical path, url = $url, is Exist = $isExist\n");
