Hi, I want to navigate to a new screen and clear the back stack. Am I doing it in a right way? Code in 🧵

[Erlan Amanatov]

NavHost(
    navController = navController,
    route = "nav_host",
    startDestination = startDestination
) {...}

and later

navController.navigate(TargetScreen){
    popUpTo("nav_host")
}

You shouldn't be popping your start destination off the back stack at all as per the Principles of Navigation: https://developer.android.com/guide/navigation/navigation-principles#fixed_start_destination

Can you explain what you're trying to do?

@Ian Lake
At the start destination, I'm checking the current user because the next screen depends on the user's role.
I want to navigate to that start destination later only on <Logout> event.

That page also talks about how login should never be your start destination, a topic we've talked about here a number of times: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1617812338353700?thread_ts=1617805109.343700&amp;cid=CJLTWPH7S

Login is not a start destination in the scheme

trying to get some clarity - why can't you navigate to the start destination while popping all other screens from the stack?
Also, your screenshot reads "close app on backpress" - if you want to close the app, you can call finish on your activity
