❓ Question: [Navigation Compose]: How can i get number of items in the backstack using NavHostController?

[theapache64]

navController.backQueue.size ??

[Ian Lake]

That is purposefully not public API

[Ian Lake]

It sounds like a case of https://xyproblem.info/

[Ian Lake]

What are you trying to do that led you to that question?

[theapache64]

Okay 😄 I’ll come back with the problem

[theapache64]

but backQueue is public 🤔

[Ian Lake]

You missed the one line above that (https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:navigati[…]time/src/main/java/androidx/navigation/NavController.kt;l=108)

@get:RestrictTo(RestrictTo.Scope.LIBRARY_GROUP)

[Ian Lake]

It is exposed only as part of the navigation-testing library in TestNavHostController

[theapache64]

but, then why am not getting any warnings when I try to access in application module? 🤔

[Adam Powell]

consider it the androidx version of `@RequiresOptIn annotation class InternalNavigationApi`; it can change without warning in any update of the library and is not intended to be used outside of the library group
