NavController has a getViewModelStoreOwner with which you can retrieve a view model (via a ViewModelProvider)

Maybe you can try this way 🤷

Yes I am doing this in my current project. You only need one initial Activity which uses setContent { ... } to open a Composable scope. From here you can use NavHost/Controller as per the documentation. Developer interaction with Activity is minimal, and interaction with Fragments is none. I'm actually using two nested NavHosts; one manages the top-level flow of the App, another handles bottom-bar navigation, between content panes within the main screen. In summary; a 'normally complex' App navigation, made purely in Compose. For ViewModels I'm currently accessing a ViewModelProvider.Factory from Ambient, but this might be better moved to NavController as @satyan said.

"For ViewModels I'm currently accessing a ViewModelProvider.Factory from Ambient" Do you have any sample code for this?
