requireFragmentManager
Deprecated
This has been renamed to getParentFragmentManager() to make it clear that you are accessing the FragmentManager that contains this Fragment and not the FragmentManager associated with child Fragments.
Return the FragmentManager for interacting with fragments associated with this fragment's activity. Note that this will be available slightly before getActivity, during the time from when the fragment is placed in a FragmentTransaction until it is committed and attached to its activity.
If this Fragment is a child of another Fragment, the FragmentManager returned here will be the parent's getChildFragmentManager.
