Have you used alternative methods for managing fragments besides FragmentManager?

Yes, besides the standard FragmentManager, in Android, alternative ways to manage fragments can be used:

• Navigation Component — a modern tool from Android Jetpack that simplifies navigation and fragment management through NavController and navigation graphs.
• ViewPager2 — for managing a set of fragments with swipe functionality.
• FragmentContainerView — a container for fragments that integrates better with the Navigation Component.

Example of using the Navigation Component:

val navController = findNavController(R.id.nav_host_fragment)
navController.navigate(R.id.action_firstFragment_to_secondFragment)

This allows abstracting from direct calls to FragmentManager and managing navigation declaratively.
