Your question

I am trying to backup my flutter app db file programmatically to a user selected folder like documents folder and i am using file_picker for selecting the folder. The problem is that on Android 16 no storage permission is required by my app as the permission is handled by file_picker itself. However, i was testing the app on a physical device running Android 8.1.0 and after selecting the folder the copy operation throws an exception (PathAccessException OS Error: Permission denied, errno13). If i use the permission_handler package to request WRITE_EXTERNAL_STORAGE then the issue is resolved for Android 8.1.0 physical device but on Android 16 device this permission is automatically denied even if the user allows the permission to file_picker.
The point is that permission_handler should return this permission as granted, not denied on later android versions where this permission is no longer need. Does permission_handler have a mechanism to automatically handle such situations? How to resolve it?
