key: String,
@IdRes navGraphId: Int
): Lazy<VM> = lazy {
val backStackEntry = findNavController().getBackStackEntry(navGraphId)
ViewModelProvider(
owner = backStackEntry,
factory = HiltViewModelFactory(requireActivity(), backStackEntry)

Description
Component used: hilt-navigation-fragment
Version used: 1.2.0
