import androidx.compose.material3.BottomAppBar



@Composable
fun BottomNavigationView(navController: NavController) {
    var selectedRoute by remember {
        mutableSetOf("home")
    }
    val items = listOf(
        NavigationItem.Home,
        NavigationItem.Search,
        NavigationItem.Add,
        NavigationItem.Activities,
        NavigationItem.Profile
    )
    BottomAppBar {
        items.forEach {
            BottomNavigationItem(
                icon = (
                        Icon(painter = painterResource(id = it.icon), contentDescription = it.title)
                        ),
                selected = selectedRoute == it.route,
                onClick = {
                    navController.navigate(it.route) {
                        navController.graph.startDestinationRoute?.let { route ->
                            selectedRoute = route
                            popUpTo(route) {
                                saveState = true
                            }
                        }

        }
    }
