so i have a pretty basic misunderstanding towards how state is used inside of an Activity, I have the following:

class MainActivity @Inject constructor() : ComponentActivity() {

    private val viewModel: MainViewModel by viewModels()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        setContent {
            if (viewModel.uiState.collectAsState().value.authenticated) {
                Home()
            } else {
                Authentication()
            }
        }
    }
}

this authenticated field is going to change to true or false inside the viewModel depending if the user is authenticated or not

the above code will first come up with false for that field, showing the Authentication composable and then the change will happen triggering the recomposition and then it will come up with true and show the Home composable

how do I listen to changes for that field, is the above even correct or how things should be done?

either authenticated needs to be backed by a MutableState, or whatever holds authenticated (the type of uiState) should be immutable and the entire object updated when the authentication status changes.
