@arnaudgiuliani I looked into this and saw that the class should have this field. I have to figure that this would be fixed by stabilization in the navigation library.

Able to reproduce on my side as well

It's mainly due to the fact that the Navigation component library was significantly refactored in recent version and the getArguments() method was removed from ViewModelStoreOwner.

public interface ViewModelStoreOwner {

    /**
     * The owned [ViewModelStore]
     */
    public val viewModelStore: ViewModelStore
}

But, koin continues to use it:

@OptIn(KoinInternalApi::class)
fun defaultNavExtras(viewModelStoreOwner: ViewModelStoreOwner): CreationExtras = when {
    viewModelStoreOwner is NavBackStackEntry && viewModelStoreOwner.arguments != null -> viewModelStoreOwner.arguments?.toExtras(viewModelStoreOwner) ?: CreationExtras.Empty
    viewModelStoreOwner is HasDefaultViewModelProviderFactory -> viewModelStoreOwner.defaultViewModelCreationExtras
    else -> CreationExtras.Empty
}

Actually, koin-compose-viewmodel:4.0.0-RC1 cannot be use with an updated Android project.

@sayah-y

I am looking at the documentation and the NavBackstackEntry still implements ViewModelStoreOwner and has the getArguments() function according to what I found here.

https://developer.android.com/reference/androidx/navigation/NavBackStackEntry

When I debugged the code the is NavBackstackEntry is true, is there a better place to pull documentation?

[arnaudgiuliani]

yes known issue on current jetbrains API
