In jetpack navigation compose, how do I do the following in a typesafe manner (using classes, not strings … this is from JetSnackNavController)

fun navigateToBottomBarRoute(route: String) {
        if (route != navController.currentDestination?.route)

The goal is to prevent the user from pressing the same top level Route over and over, which based on the typical Bottom Nav code I see, causes the `compose`<> block to rerun, viewmodels to be recreated, etc.

Hello!
In my app, I'm using the hasRoute() API, which is very useful for comparing the typesafe with the BackStackEntry. Something like:

navHostController.currentBackStackEntry?.destination?.hasRoute(route::class) == true

Ah thanks very much! I was looking at hasRoute, but could not figure out how I would use it with multiple routes using the same class (different default args). I probably should not do that
