React导航5定义屏幕时传递参数

// 安装依赖
// npm install @react-navigation/native @react-navigation/stack

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

const Stack = createStackNavigator();

      <Button
        title="Go to Details"
        onPress={() => navigation.navigate('Details', { itemId: 86 })}
      />

// 确保在DetailScreen中正确解构参数
function DetailScreen({ route }) {

  // ...
}

  }, [route]);

  const { itemId } = route.params;
