react-native react-navigation6.x 路由跳转及传参

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import React from 'react';
import { Button } from 'react-native';
 
// 定义导航器
const Stack = createStackNavigator();
 
// 定义两个屏幕
function HomeScreen({ navigation }) {
  return (
    <Button
      title="Go to Details"
      onPress={() => navigation.navigate('Details', { itemId: 123 })}
    />
  );
}
 
function DetailsScreen({ route, navigation }) {
  // 获取传递的参数
  const { itemId } = route.params;
  // 使用参数
  return (
    <Button
      title="Go to Details"
      onPress={() => navigation.navigate('Details', { itemId: itemId + 1 })}
    />
  );
}
 
// 导出应用
export default function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Details" component={DetailsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

这个例子展示了如何在React Native应用中使用React Navigation 6.x进行路由跳转及参数传递。HomeScreen组件中使用navigation.navigate方法跳转到DetailsScreen，并传递了一个名为itemId的参数。DetailsScreen组件接收到route.params后使用该参数，并且可以继续跳转并传递新的参数。
