I just realised there's one class Called

ComposeNavigator

which is supposed to handle backstack and create destination. Where can I find the example usage of it?

There's a whole docs page on Navigating with Compose: https://developer.android.com/jetpack/compose/navigation

Yes, I'm aware of that, so you mean

ComposeNavigator

is the class powering navigation-compose? I thought this is some unexplored API and has any other use-case

it’s just like FragmentNavigator, it’s implementation detail

Yep, that's what

NavHost

uses under the hood
