javascript - React Navigation如何从堆栈导航内部隐藏标签栏

Question

我有以下堆栈导航和屏幕:

export const HomeStack = createStackNavigator({
    Home: HomeScreen,
    Categories: CategoriesScreen,
    Products: ProductsScreen,
    ProductDetails: ProductDetailsScreen,
})

我只想在 ProductDetailsS​​creen 中隐藏标签:

export const hideTabBarComponents = [
    'ProductDetails',
]

export const MainTabs = createBottomTabNavigator(
    {
        Home: HomeStack,
        Favorite: FavoriteScreen,
        Account: AccountScreen,
        Help: HelpScreen,
        Events: EventsScreen
    },
    {
        navigationOptions: ({ navigation }) => ({

            tabBarIcon: ({ focused, tintColor }) => {
                ...
            },
            tabBarLabel: ({ focused, tintColor }) => {
                ...
            },
            
            tabBarVisible: ! hideTabBarComponents.includes(navigation.state.routeName)

        }),
    }
);

问题是无法从堆栈导航将任何选项传递给选项卡导航
并非所有堆栈屏幕都只有其中一个

下面的代码解决了这个问题:

HomeStack.navigationOptions = ({ navigation }) => {

    let tabBarVisible = true;

    let routeName = navigation.state.routes[navigation.state.index].routeName

    if ( routeName == 'ProductDetails' ) {
        tabBarVisible = false
    }

    return {
        tabBarVisible,
    }
}
