如何在Jetpack Compose上按下按钮时弹出堆栈

val stack = remember { mutableStateListOf<@Composable () -> Unit>() }

Button(onClick = {
    stack.add { NextScreen() }
}) {
    Text("按下按钮")
}

NavHost(navController = rememberNavController()) {
    composable(route = "currentScreen") {
        stack.lastOrNull()?.invoke()
    }
}

fun popBackStack(navController: NavController) {
    stack.removeLastOrNull()
    navController.popBackStack()
}

Button(onClick = {
    popBackStack(navController)
}) {
    Text("返回")
}
