如何在Flutter中将社交媒体链接/按钮添加到我的应用程序？

import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Social Media Button Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text('Social Media Button Demo'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              SocialMediaButton(
                icon: Icons.facebook,
                url: 'https://www.facebook.com',
              ),
              SizedBox(height: 16),
              SocialMediaButton(
                icon: Icons.twitter,
                url: 'https://www.twitter.com',
              ),
            ],
          ),
        ),
      ),
    );
  }
}

class SocialMediaButton extends StatelessWidget {
  final IconData icon;
  final String url;

  const SocialMediaButton({required this.icon, required this.url});

  @override
  Widget build(BuildContext context) {
    return IconButton(
      icon: Icon(icon),
      onPressed: () {
        launch(url);
      },
    );
  }
}
