如何在React导航5中使用上下文API

npm install react-navigation

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import React from 'react';

const Stack = createStackNavigator();

const MyContext = React.createContext();

const App = () => {
  return (
    <MyContext.Provider value={/* 上下文值 */}>
      <NavigationContainer>
        <Stack.Navigator>
          {/* 导航屏幕 */}
        </Stack.Navigator>
      </NavigationContainer>
    </MyContext.Provider>
  );
};

const Screen = () => {
  const contextValue = React.useContext(MyContext);
  
  // 使用上下文值进行操作
  
  return (
    // 屏幕内容
  );
};
