Hi, I'm trying to use rememberSaveable with Enum but it's not working, not sure what I'm doing wrong here.

var selectedDashboardTab = rememberSaveable(TabSaver) { mutableStateOf(DashboardTab.HOME) }

val TabSaver = Saver<DashboardTab, Int>(
    save = {
        if (it == DashboardTab.HOME) {
            0
        } else 1

    },
    restore = {
        if (it == 0) {
            DashboardTab.HOME
        } else {
            DashboardTab.STORE
        }
    }
)

Going to screen B and coming to Screen A doesn't save the state.

It's probably because stateSaver is the second parameter. You should explicity add stateSaver = TabSaver .

as far as I remember enums are serializable, so it should work without custom saver

After wasting so much time I get rid of it 😞 I tried stateSaver , saver, without Custom saver nothing works.
