Android 弹出导航堆栈后，Compose 无法访问 Hilt View Model

我的应用程序中有这样的代码:

@Composable
fun LogInScreen(
    navController: NavHostController,
) {
    val backStackEntry = remember(navController.currentBackStackEntry) {
        navController.getBackStackEntry(MainAppNavOptions.AuthScreen.name)
    }
    val viewModel: AuthViewModel = hiltViewModel(backStackEntry)
    ...
    LaunchedEffect(key1 = viewModel.isUserSignInState.value){
        if (viewModel.isUserSignInState.value){
            navController.navigate(MainAppNavOptions.MainScreen.name){
                popUpTo(MainAppNavOptions.MainScreen.name){
                    inclusive = true
                }
            }
        }
    }
    ...
}

所以在这里，我得到了身份验证屏幕的共享视图模型，然后在成功登录后导航到我的主屏幕.

但看起来好像LogInScreen函数又运行了一次，因为我正在弹出后台堆栈，它无法获得视图模型并抛出一个错误:

以下是一些注意事项:

• 是的，如果我不弹出堆栈，它是有效的，但它是必需品
• 我试过加if (viewModel.isUserSignInState.value) return，但我认为这不是最好的办法……
