HiltNavGraphViewModelLazyKt

@MainThread
public static final @NonNull Lazy<@NonNull VM> <VM extends ViewModel> hiltNavGraphViewModels(
    @NonNull Fragment receiver,
    @IdRes int navGraphId
)

Returns a property delegate to access a HiltViewModel -annotated ViewModel scoped to a navigation graph present on the NavController back stack:

class MyFragment : Fragment() {
    val viewmodel: MainViewModel by hiltNavGraphViewModels(R.navigation.main)
}

This property can be accessed only after this NavGraph is on the NavController back stack, and an attempt access prior to that will result in an IllegalArgumentException.
