NavController.currentBackStackEntryAsState() might help. What are you trying to observe?

trying to observe current destination route composable to hide show some UI elements based of a route

Yep, that's exactly what currentBackStackEntryAsState() is for. You can see the example in the docs on how to get the route: https://developer.android.com/jetpack/compose/navigation#bottom-nav

okay, how can I get current String “route” from this State holder so I can perform some logic ?

[Tim Malseed]

@Composable
fun NavHostController.currentRoute(): String? {
    val navBackStackEntry by currentBackStackEntryAsState()
    return navBackStackEntry?.arguments?.getString(KEY_ROUTE)
}
