如何在React Native中显示一次屏幕？

// Step 1: 创建一个新的React Native项目并安装所需依赖

// Step 2: 编写屏幕组件
import React from 'react';
import { View, Text } from 'react-native';

const MyScreen = () => {
  return (
    <View>
      <Text>Hello, React Native!</Text>
    </View>
  );
};

export default MyScreen;

// Step 3: 导航到屏幕
import { createStackNavigator } from '@react-navigation/stack';
import MyScreen from './MyScreen';

const Stack = createStackNavigator();

const AppNavigator = () => {
  return (
    <Stack.Navigator>
      <Stack.Screen name="MyScreen" component={MyScreen} />
    </Stack.Navigator>
  );
};

export default AppNavigator;

// Step 4: 在应用程序中显示屏幕
import { NavigationContainer } from '@react-navigation/native';
import AppNavigator from './AppNavigator';

const App = () => {
  return (
    <NavigationContainer>
      <AppNavigator />
    </NavigationContainer>
  );
};

export default App;
