所有屏幕上的diplay底部导航器反应本机

Question

我有1个stackNavigator（appStack（10个屏幕），1个登录页面（loginScreen）和1个BottomTabNavigator（MainTabs（3个屏幕））

我想在所有屏幕上显示我的BottomTabNavigator（appStack + Maintabs） 所以我想在除登录屏幕之外的所有屏幕上显示带有3个按钮的底部栏

但是目前，经过很多尝试，我只能在MainTabs上显示底部导航器

有什么主意吗？ 谢谢

    const appStack = createStackNavigator({
    TaskAndNotifScreen: {
        screen: TaskAndNotifScreen,
        navigationOptions: {
            header: () => null
        }
    },
    ProfilScreen: {
        screen: ProfilScreen,
        navigationOptions: {
            visible: false,
            header: () => null
        }
    },
    ProfilApplicantScreen: {
        screen: ProfilApplicantScreen,
        navigationOptions: {
            visible: false,
            header: () => null
        }
    },
    SpecificVacancyScreen: {
        screen: SpecificVacancyScreen,
        navigationOptions: {
            visible: false,
            header: () => null
        }
    },
    CvthequeScreen: {
        screen: CvthequeScreen,
        navigationOptions: {
            visible: false,
            header: () => null
        }
    },

    OffreColumnScreen: {
        screen: OffreColumnScreen,
        navigationOptions: {
            visible: false,
            header: () => null
        }
    },
})

const MainTabs = createBottomTabNavigator({
    OffreScreen: {
        screen: OffreScreen,
        navigationOptions: {
            header: () => null
        }
    },
    ProfilScreen: {
        screen: ProfilScreen,
        navigationOptions: {
            header: () => null
        }
    },
    CvthequeScreen: {
        screen: CvthequeScreen,
        navigationOptions: {
            header: () => null
        }
    },

});

const App = createSwitchNavigator({
    login :{
        screen : HomeScreen
    },

    appstack: {
        screen: appStack,
    },
    App: {
        screen: MainTabs, 
    },
});



const Router = createAppContainer(App);
