What methods of transitioning between fragments do you know and use in your projects?

In Android, transitioning between fragments is usually done using FragmentManager and FragmentTransaction. Main methods include:

• replace() — replaces the current fragment with a new one. Often used for navigation within a single container.

• add() — adds a new fragment on top of the current one without removing the previous.

• addToBackStack() — adds the transaction to the back stack, so pressing "back" returns to the previous fragment.

• Navigation Component — a modern navigation method using a navigation graph, simplifying transitions and back stack management.

Example of replacing a fragment with back stack addition:

supportFragmentManager.beginTransaction()
    .replace(R.id.fragment_container, NewFragment())
    .addToBackStack(null)
    .commit()

In projects, Navigation Component is often used as it simplifies navigation, especially in complex scenarios with multiple fragments.
