Last time I checked graph id is not available in Compose Navigation in common, so we can't pop all graph properly, is it still the case?

[Ivan Matkov]

Yes, it's not planned to be exposed to common.

this id initially was about xml resource id that is simply not a case for compose and/or multiplatform.

For compose navigation unique id is route , id for android is maintained as just hash from it.

so we can't pop all graph properly

Could you please clarify? All methods have overloads for route, int id is not required for any operation AFAIK

[mohamed rejeb]

How can I clear all the routes, for now I'm doing this with a loop and popBackStack which is not efficient, Also the first route can be different and can be present multiple times on that stack, so popUntil and passing the first route to it is not going to work in a lot of cases.
In voyager they have nice things such us popAll, replaceAll...

[Ivan Matkov]

So how exactly int id will help you with it?

[mohamed rejeb]

That's how we used to do it on Android:
popUpTo(navHostController.graph.id)

[Ivan Matkov]

Why popUpTo(navHostController.graph.route) doesn't work for you?

[mohamed rejeb]

This is the start destination right?

[mohamed rejeb]

As I said the first route can be totally different than the start destination, for example I have SplashScreen as a start destination and I will directly pop it after few seconds.
Also I have cases where the same screen can be present multiple times.
A->...->A->B after popupto(A): A->...->B

[Ivan Matkov]

No it's not start dest. It's set from NavHost(route) arg (null by default)

[mohamed rejeb]

Ah ok that's what I want I guess. I didn't know about it. I will check it out.

If you're interested, it's the place I mentioned. id is just hash from this route on Android

[Konstantin Tskhovrebov]

navController.navigate(NewRoot) {
  popUpTo(navController.graph.id) {
    inclusive = true
  }
}

[Ivan Matkov]

@Konstantin Tskhovrebov no id in common. It's the topic of this thread

[Konstantin Tskhovrebov]

this code works in common in my project

[Ivan Matkov]

Kinda. Technically we have this "id" for internal needs. It's marked as @RestrictTo(RestrictTo.Scope.LIBRARY_GROUP) and not supposed to be used externally. Not sure why IDE doesn't complain

[Konstantin Tskhovrebov]

a. ok. I didn't notice it 🆗

[Ivan Matkov]

+ it's not in common, but in platform source set
