Nested fragment ScreenSwitcher

[DomiBlaze]

Is it possible to implement nested FragmentScreenSwitcher?
One of my fragments(let's call it HostFragment) has a bottom navigation implemented, and I want to use switchTo to switch betweed child fragments of HostFragment.
Furthermore, I have AnotherHostFragment with different set of fragments.
I want to solve this problem without additional activities, in a single activity app setup.

Thank you in advance

You can extend FragmentScreenSwitcher to delegate switching of inner fragments to additional screen switchers. Like that:

public interface ScreenSwitcherProvider {
	ScreenSwitcher getScreenSwitcher();
}

public class MainScreenSwitcher extends FragmentScreenSwitcher {

	// constructors are ommited
	
	@Override
	public void switchTo(Screen screen, @Nullable AnimationData animationData) throws NavigationException {
		if (isInner(screen)) {
			ScreenSwitcher screenSwitcher = ((ScreenSwitcherProvider) getCurrentFragment()).getScreenSwitcher();
			screenSwitcher.switchTo(screen, animationData);
		} else {
			super.switchTo(screen, animationData);
		}
	}
}
