createBottomTabNavigator 在单击时不呈现 createStackNavigator

Question

我正在学习 react-navigation 教程并且一切正常，直到我尝试使用 createBottomTabNavigator ，我将两个 createStackNavigator 传递给 createBottomTabNavigator，第一个屏幕显示膳食类别呈现没有任何问题，但是当我按“收藏夹”选项卡（带有星形图标的那个）时，我看到空白屏幕，FavNavigator 根本没有呈现。
我尝试用 FavoritesScreen 组件替换 FavNavigator 并且它正在显示，但缺少 header 栏。

这是应用程序：

这里是导航器配置代码：

import React from "react";
import { createStackNavigator } from "react-navigation-stack";
import { createBottomTabNavigator } from "react-navigation-tabs";
import { createAppContainer } from "react-navigation";
import { Ionicons } from "@expo/vector-icons";
import { createMaterialBottomTabNavigator } from "react-navigation-material-bottom-tabs";

import CategoriesScreen from "../screens/CategoriesScreen";
import CategoryMealsScreen from "../screens/CategoryMealsScreen";
import MealsDetailScreen from "../screens/MealsDetailScreen";
import FavoritesScreen from "../screens/FavoritesScreen";
import Colors from "../constans/Colors";
import { Platform } from "react-native";

const defaultStackNavOptions = {
  headerStyle: {
    backgroundColor: Platform.OS === "android" ? Colors.primaryColor : ""
  },
  headerTintColor: Platform.OS === "android" ? "white" : Colors.primaryColor,
  headerTitle: "A Screen"
};

const MealsNavigator = createStackNavigator(
  {
    Categories: {
      screen: CategoriesScreen
    },
    CategoryMeals: {
      screen: CategoryMealsScreen
    },
    MealDetail: MealsDetailScreen
  },
  {
    defaultNavigationOptions: defaultStackNavOptions
  }
);

const FavNavigator = createStackNavigator(
  {
    Favorites: FavoritesScreen,
    MealDetail: MealsDetailScreen
  },
  {
    defaultNavigationOptions: defaultStackNavOptions
  }
);

const tabScreenConfig = {
  Meals: {
    screen: MealsNavigator,
    navigationOptions: {
      tabBarIcon: tabInfo => {
        return (
          <Ionicons name="ios-restaurant" size={25} color={tabInfo.tintColor} />
        );
      },
      tabBarColor: Colors.primaryColor
    }
  },
  Favorites: {
    screen: FavNavigator,
    navigationOptions: {
      tabBarIcon: tabInfo => {
        return <Ionicons name="ios-star" size={25} color={tabInfo.tintColor} />;
      },
      tabBarColor: Colors.accentColor
    }
  }
};

const MealsFavTabNavigator =
  Platform.OS === "android"
    ? createMaterialBottomTabNavigator(tabScreenConfig, {
        activeTintColor: "white",
        shifting: true,
        barStyle: {
          backgroundColor: Colors.primaryColor
        }
      })
    : createBottomTabNavigator(tabScreenConfig, {
        tabBarOptions: {
          activeTintColor: Colors.accentColor
        }
      });

export default createAppContainer(MealsFavTabNavigator);

提前致谢。

我今天遇到了类似的问题。我通过 downgrading/upgrading react-native-screens 将其保存为版本："react-native-screens"：“2.1.0”。之前是 2.4
