It would be nice to have one. ;)

Have you work in something with BottomNavigation and compose-router?

I have not.

I did this behaviour using Rxjava and JetPack BottonNavigation if you are interested

Hello, I just managed the back stack as necessary for BottomNavigation, meaning the user always goes back to Home before leaving the app, and all other options than Home are replacing each other:

fun <T> BackStack<T>.pushBottomBar(root: T, others: List<T>, item: T) {
    if (item == root || last() != item ) {
        when {
            root == item -> {
                val removeHowMany = elements.size - elements.indexOf(item)
                repeat(removeHowMany) { pop() }
            }
            elements.any(others::contains) -> {
                replace(item)
            }
            else -> push(item)
        }
    }
}

And here's the BottomNavigation:

BottomNavigation {
    menuItems.forEach { item ->
        BottomNavigationItem(
            icon = { Icon(vectorResource(id = item.iconResId)) },
            text = { Text(stringResource(id = item.label)) },
            selected = currentRouting == item,
            onSelected = { backStack.pushBottomBar(defaultRouting, menuItems - defaultRouting, item) }
        )
    }
}

Hope this helps!
