ActivityViewModelContext

data class ActivityViewModelContext(activity: ComponentActivity, args: Any?, owner: ViewModelStoreOwner, savedStateRegistry: SavedStateRegistry) : ViewModelContext

The ViewModelContext for a ViewModel created with an activity scope (val viewModel by activityViewModel<MyViewModel>). Although a fragment reference is available when an activity scoped ViewModel is first created, during process restoration, activity scoped ViewModels will be created without a fragment reference, so it is only safe to reference the activity.
