Flutter_downloader 下载一直失败

Question

Flutter_downloader 没有下载我的文件，这是我运行代码时的日志::

这是代码::

await FlutterDownloader.enqueue(
    url: _url, //url is https://tooxclusive.com/wp-content/uploads/2022/03/Asake-Sungba.mp3
    savedDir: '/storage/emulated/0/Download',
    showNotification: true,
    saveInPublicStorage: true
);

Answer 1

工人显示成功。 由于您正在访问下载文件夹，请在清单中添加互联网，读取和写入权限

    <uses-permission android:name="android.permission.INTERNET"/> 
  
     <!-- Permissions options for the `storage` group --> 
     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 
     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Answer 2

做一件事。 在void main()下添加两行

 await FlutterDownloader.initialize(
      debug: true // optional: set false to disable printing logs to console
      );

  FlutterDownloader.registerCallback(DownloadClass.callback);

将 DownloadClass 设为顶级函数，如下图所述。

希望这能解决您的问题。

谢谢
