ViewModelStore

Class to store ViewModels.

Instances of ViewModelStore must be retained through configuration changes. If the owner of a ViewModelStore, typically a `ViewModelStoreOwner`, is destroyed and recreated due to a configuration change, the new owner must have the old instance of the ViewModelStore.

If the owner of a ViewModelStore is destroyed and is not going to be recreated, it should call `clear` on this ViewModelStore so that The ViewModels stored by it are notified that they are no longer needed.

Use `ViewModelStoreOwner.getViewModelStore` to retrieve a ViewModelStore for activities and fragments.
