I am testing about

1. Create A folder.
2. Upload files in the A folder.
3. Delete files in the A folder.
4. Delete A folder.

1-3 steps are fine.
But I got an error from the 4 step.

PathAccessException: Cannot delete file, path = 'folder' (OS Error: Access is denied.
, errno = 5)

So, one solution I want is setting folder permission to remove it.

This is what I think:

1. Create A folder.
2. Upload files in the A folder.
3. Delete files in the A folder.
4. Set permission of A folder.
5. Delete A folder.

But I found GitHub issue. They will not add a setting permission feature. So, is there any solution to delete this folder by using the Dart server?

This is my code about creating a new folder:

bool? createFolder(String path) {
  try {
    final folder = Directory(path);
    if (folder.existsSync()) return null;
    folder.createSync(recursive: false);
    if (!folder.existsSync()) return false;
    return true;
  } catch (e) {
    print('Error:n$e');
    return false;
  }
}

and the delete folder function:

bool deleteFolder(String path) {
    try {
      final directory = Directory(path);
      if (directory.existsSync()) File(path).deleteSync();
      if (directory.existsSync()) return false;
      return true;
    } catch (e) {
      print('Error:n$e');
      return false;
    }
  }

PS. I found GitHub issue.
