Like I said in your issue, judging from this log line “audio” couldn’t be moved because you don’t have permission to access “tmp” this is likely related to missing file/directory access. It has nothing to do with dio.

Infact, when flutter app run the below source,the error is happened.So I think when the dio download ,Tmp file is created. But not set the permission.
return await dio.download('http://xxx.xxx.xxx.xxx:8080/wav/2007011783233556_176_2369.mp3', '$_selectedDirectory/xx.mp3',
onReceiveProgress: (int loaded, int total) {
// print("下载进度：" +
// NumUtil.getNumByValueDouble(loaded / total * 100, 2)
// .toStringAsFixed(2) +
// "%");
});

This depends on the adapter you are using. You are responsible for requesting the appropriate permissions. Dio can not do that for you.

If you are using objectAtIndex:0 to get the first item in an array, you can try using firstObject instead of.
