使用此程序包 path_provider ，我得到了这3条路径:

推荐答案
您可以使用 downloads_path_provider 包裹.您将在您的AndroidManifest.xml中添加< uses-permission android:name ="android.permission.READ_EXTERNAL_STORAGE"/> .另外，如果您打算写入该文件夹并希望您的应用程序适用于Android版本> 6，则必须征求用户的写入许可.您可以使用 https://pub.dev/packages/permission_handler 来做到这一点.等待PermissionHandler().requestPermissions([PermissionGroup.storage]);
You could use the downloads_path_provider package. You will have add <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> to your AndroidManifest.xml. Also if you plan to write into that folder and want your application to work for android version > 6 you must ask the user for writing permission. You could do that with https://pub.dev/packages/permission_handler.
await PermissionHandler().requestPermissions([PermissionGroup.storage]);
