I'm getting this lint error, but when I fix the error... it still remains. Am I misunderstanding the issue or does the lint check/lint itself have a bug?

You need a key as well

[Colton Idle]

🤔

[Colton Idle]

Oh wait. So remember takes an arg? (TIL)

[Colton Idle]

So is this the intended fix?

val sharedVM = remember(navController.currentBackStackEntry) { navController.getBackStackEntry(Screen.LoggedOutScreens.route) }

[Colton Idle]

It does make the error go away. so i suppose so?

[Colton Idle]

Alright. I don't think that was the right thing, because I started getting some stacktrace after just trying to call navController.popBackStack (something about route not found)

I went back to just a remember{} without an arg then used `

@SuppressLint("UnrememberedGetBackStackEntry")

and everything works as expected.

Im sure thi will bite me and maybe Ian will have more insight (or someone else), but since I have a demo for tomorrow I will keep this for now.

Can you share more code context around that block of code? Is it in a composable(...) { }?

If so I believe this is the right approach:

composable(...) { navBackStackEntry ->
  val sharedVM = remember(navBackStackEntry) { navController.getBackStackEntry(Screen.LoggedOutScreen.route) }
}

Sorry, yes. You need to pass in a key to remember so it updates correctly. Something like what Chris is suggesting is the way to go
