Hi All,  trying to transition from one screen to another (Login -≥ Main) So once the Login Button has been clicked it sets login = true and I have. if(login) { MainScreen(). }. Where MainScreen is a composable.  I expect the screen to fully change from the Login Composable/UI to the Main Composable/UI. but end up with a half and half the top half is still Login the Bottom is part of Main.  I don't need navgiation or a back stack as Main will start that.  Please Advices,  Thanks

Can you share screen shot ? Seems issue is with the screens that you have designed

Here is the Login Screen  I tap Login and then get the second image which is Login in squished to the top and Main squished to the bottom. both screen at once in stead of Login becoming Main

It seems the issue is in modifiers, hope Login and Main screen are not in same parent view

LoginScreen starts with
```MaterialTheme(
    colorScheme = theme,
) {
    Column(
        modifier = Modifier
            .fillMaxSize()
            .background(AppColors.silver)
    ) {```
MainScreen starts with
```MaterialTheme(
    colorScheme = theme,
) {
    Scaffold(
        modifier = Modifier.fillMaxSize(),
        topBar =  {```


sorry no just beginning to see if a KMP will work to combine two native codes sources into one.

```MaterialTheme(
    colorScheme = if (isDark) DarkColorScheme else LightColorScheme,
) {
    var login by remember { mutableStateOf(false) }
    if (login) {
        Column(Modifier.fillMaxSize()) { /* your login screen*/}
    } else {
        Scaffold(Modifier.fillMaxSize()) {/* Your main screen*/ }
    }
}```
Try this way and there should always be one material theme in your app.

I will also suggest using <https://voyager.adriel.cafe|voyager> it is the best screen, viewmodel and navigation for KMP and android.
