This codebase is realted to one weird flow in Android 11 permissions handling.

In android 11 this is the weird flow- permissions popups are dismissible, and when we dismiss we get callback like user selected never ask again 😁

I wrote a blog on it with solution, where you check more about this problem and its workaround solution.

Check blog here with Solution :)

also While requesting permissions there is slight difference please note that as well, than only you will get callback in onRequestPermissionsResult method.

in activity -

ActivityCompat.shouldShowRequestPermissionRationale(requireActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)

and in fragment -

requestPermissions(arrayOf(Manifest.permission.READ_EXTERNAL_STORAGE), READ_STORAGE_PERM)

If we follow this way of requesting permissions based on Activity/Fragment it will surely give us the callback. #verified.
