Hey guys,

I have a `ComposeView` which contains a `NavHost`  with a `NavController` inside. Is it normal that the  `NavController`s  `viewModelStore` s are not cleared when that `ComposeView` is removed from the layout hierarchy?

I am doing that as a workaround:
```navController.currentBackStack.value.forEach { 
   it.viewModelStore.clear()
}```
but we are not supposed to access the `currentBackStack` from the outside of the library with _groupid = androidx.navigation_

is there a better way to tackle that?

That still won't clear any saved back stacks (destinations you've saved with `saveState` ala bottom navs) - that's why that's the wrong API to use, even if it was public

What you need is the parent ViewModelStoreOwner to be cleared. That could be when a Fragment that owns the ComposeView is removed from its FragmentManager or the whole activity is finished

But adding and removing a View isn't enough, even in the View world (that's why things like Fragments exist)
