React-Native:有没有bottomTabNavigator的运行示例？

npm install @react-navigation/native
npm install @react-navigation/bottom-tabs

import React from 'react';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import { NavigationContainer } from '@react-navigation/native';

// 导入需要显示在底部导航栏的页面组件
import HomeScreen from './screens/HomeScreen';
import ProfileScreen from './screens/ProfileScreen';

const Tab = createBottomTabNavigator();

function App() {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Home" component={HomeScreen} />
        <Tab.Screen name="Profile" component={ProfileScreen} />
      </Tab.Navigator>
    </NavigationContainer>
  );
}

export default App;

import React from 'react';
import { View, Text } from 'react-native';

function HomeScreen() {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

export default HomeScreen;

import React from 'react';
import { View, Text } from 'react-native';

function ProfileScreen() {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Profile Screen</Text>
    </View>
  );
}

export default ProfileScreen;
