BottomAppBar 配合NavigationBarItem 切换设置popUpTo的问题

[LiuPack]

添加了底部切换导航功能，代码如下

@Composable
fun MainScreen() {
    val navigator = rememberNavigator()
    val viewModel = koinViewModel(MainViewModel::class)
    val currentEntry by navigator.currentEntry.collectAsState(null)
    val isNavigation = viewModel.navigationList.any { it.router.path == currentEntry?.path }
    Column(modifier = Modifier.fillMaxSize()) {
        NavHost(navigator = navigator,
            initialRoute = Router.Splash.path,
            modifier = Modifier.weight(1f),
            persistNavState = true,
            builder = {
                splashScreen(navigator = navigator)
                homeScreen(navigator = navigator)
                systemScreen(navigator = navigator)
                wechatAccountScreen(navigator = navigator)
                projectScreen(navigator = navigator)
                userScreen(navigator = navigator)
            })
        AnimatedVisibility(
            visible = isNavigation,
            enter = expandVertically(),
            exit = shrinkVertically(),
            modifier = Modifier.fillMaxWidth()
        ) {
            BottomAppBar(modifier = Modifier.fillMaxWidth()) {
                viewModel.navigationList.forEach {
                    NavigationBarItem(selected = currentEntry?.path == it.router.path, onClick = {
                        navigator.navigate(
                            route = it.router.path, options = NavOptions(
                                launchSingleTop = true,
                            )
                        )
                    }, icon = {
                        Icon(imageVector = it.icon, contentDescription = null)
                    }, label = {
                        Text(text = it.label)
                    })
                }
            }
        }
    }
}

其中NavOptions中只设置launchSingleTop，其他保持默认，底部切换加载的页面，状态都是能保持的，但是在调用系统返回时，是按照切换的顺序返回的，也就是按照栈的方式弹出的，有什么方式可以处理状态保存下按下返回键时是直接退出应用
