I tried to share some states between my screens in NavHost but it doesn't update when the appState change !!!
Any one know why it doesn't recompose when the appState change ?

It should work.
Does `AppState` itself change, or some internal state of `AppState`?
If it’s internal state, is that defined as a `MutableState` or a simple `var`?
A peek inside your `AppState` would make it easier to debug.

Could you show the call-site as well?

At a glace, the `bottombarVisibility` and `drawerVisibility` should not be `var`s, since they themselves should not be changing, but their internal state.

But there doesn’t seem to be anything wrong with the `isLandscape` part. It relies on `windowSizeClass` which is a `val` and should only be updated when you construct a whole new `AppState` object.

Can I see where you’re constructing and remembering your `AppState` object as well?

I think this is the same problem I had, which I fixed this way: <https://kotlinlang.slack.com/archives/CJLTWPH7S/p1660238432465599>

yes, It's the same problem as mine.... I didn't know how to implement your solution

This is the structure of what I did:
```@Composable
fun AppNavGraph(
    ...
    settings: Settings
) {
    val settingsAsState = rememberUpdatedState(settings)
    NavHost(...) {
        settingsNavGraph(
            ...
            settings = { settingsAsState.value }
        )
    }
    ...
}

fun NavGraphBuilder.settingsNavGraph(
    ...
    settings: () -&gt; Settings
) {
    navigation(...) {
        composable(
            route = ...,
        ) {
            SettingsScreen(
                ...
                settings = settings()
            )
        }
        ...
    }
}```


Except you do it for `appState`, not `settings`.
