# compose

I was using compose-navigation with bottom nav, I got a doubt
(As docs stated one is Profile Composable and other is FriendList Composable , using as eg.
and below as onClick code

onClick = {
              // This is the equivalent to popUpTo the start destination
                 navController.popBackStack(navController.graph.startDestination, false)
                 if (currentRoute != screen.route) {
                            navController.navigate(screen.route)
                 }
          }

)
Lets say
So startDestination is Profile , then we clicked on FriendList bottom nav item, and then we clicked Profile, then FriendList
When I press back, I never go back to FriendList, though I have visited it twice
How does popBackStack works here, popping till Profile and not including Profile

[Cyril Find]

yes popBackStack(navController.graph.startDestination, false) pops everything up to profile not including it

[Cyril Find]

it does so every time you navigate so there is never a lot of back stack entries in there

[Cyril Find]

btw with alpha02 there's a new syntax

navController.navigate(screen.route) {
                        launchSingleTop = true
                        popUpTo = navController.graph.startDestination
                    }

so you can customize it to your use case

@Cyril Find popping upto profile and suppose I have backstack like this :
Profile(start) -> Friends -> Profile -> Fragment(at top)
so if you pop upto startDestination , how it will work ?

[Cyril Find]

i think it would just pop the last Fragment but the thing is you pop eveytime you navigate

[Cyril Find]

so you just have 1 Profile in your backstack
