Bottom Navigator is a library for managing multiple Fragment backstacks controlled by the tabs of a BottomNavigationView. It has a simple API and is feature-rich.

Android FragmentManager actually provides a way to let us skip some Fragment instances when popping backstack: popBackStack(String name, int flags) If we mark AuthFragment instance and save the tag for HomeFragment instance, we can skip AuthFragment instance or any Fragment instances that already exist in the backstack, and navigate to home.
