Any guides to compose navigation with bottomNav with a sign in flow?

I used these docs when setting up my app https://developer.android.com/jetpack/compose/navigation#bottom-nav
but now when I open the app on a cold launch (and the user isn't logged in), I see my HomeScreen for a split second with my bottom nav and then I go to my sign in screen which doesn't have bottom nav and it's just kinda jarring from the user POV. Curious if there's some best practices with bottom nav and sign in combined.

Would something like this work?

val navController = rememberNavController()
Scaffold(
  bottomBar = {
if(user.isloggedIn() {
   BottomNavigation()
  }
}
)

?

[Nick]

and for the content part:

when(user.isLoggedIn){
   true -> HomeScreen()
   false -> Login()
}

[Nick]

you shouldn’t see the flicker then

[Nick]

but user.isLoggedIn should be a state though, with the default value of false

[Ian Lake]

Note that this next Navigation release removes the initial flicker caused by Navigation's state not being set for the first composition

Interesting. Maybe That's the issue. Any other tips or should I wait for that?

[Nick]

oh there’s a bug? does my solution not work?

[Colton Idle]

I was mostly just commenting on the fact that maybe my impl wasn't "wrong" at all, it's just that navigation lib needs an update.

Regarding your solution Nick, I haven't tried it but I was curious to what Ians opinion on it is. So far I have all of my user.isLoggedIn checking being done on the composable Screen level as per Ians recommendation and so I'd like to keep all of that logic there.

ahh that sounds like a better way.
