示例代码

import 'package:flutter/material.dart';
import 'package:flutter_referral_link/flutter_referral_link.dart'; // 导入flutter_referral_link插件

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;
  String? _referralLink; // 用于存储生成的推荐链接

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  // 生成推荐链接的方法
  Future<void> _generateReferralLink() async {
    try {
      String link = await FlutterReferralLink.generateReferralLink(
        campaignId: 'your_campaign_id', // 替换为您的活动ID
        userId: 'user_id', // 替换为用户的唯一标识符
      );
      setState(() {
        _referralLink = link;
      });
    } catch (e) {
      print("Failed to generate referral link: $e");
    }
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
            const SizedBox(height: 20), // 添加间距
            ElevatedButton(
              onPressed: _generateReferralLink, // 点击按钮生成推荐链接
              child: const Text('Generate Referral Link'),
            ),
            if (_referralLink != null)
              Padding(
                padding: const EdgeInsets.all(8.0),
                child: Text(
                  'Your referral link: $_referralLink',
                  style: TextStyle(fontSize: 16),
                ),
              ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}

说明

在上面的示例代码中，我们展示了如何使用flutter_referral_link插件来生成和管理推荐链接。主要步骤如下：

1. 导入插件：首先导入flutter_referral_link插件。

   import 'package:flutter_referral_link/flutter_referral_link.dart';
   

2. 生成推荐链接：创建一个方法_generateReferralLink来生成推荐链接。该方法调用FlutterReferralLink.generateReferralLink方法，并传入必要的参数（如活动ID和用户ID）。

   Future<void> _generateReferralLink() async {
     try {
       String link = await FlutterReferralLink.generateReferralLink(
         campaignId: 'your_campaign_id', // 替换为您的活动ID
         userId: 'user_id', // 替换为用户的唯一标识符
       );
       setState(() {
         _referralLink = link;
       });
     } catch (e) {
       print("Failed to generate referral link: $e");
     }
   }
   

3. 显示推荐链接：在UI中添加一个按钮，当点击时调用_generateReferralLink方法生成推荐链接。如果生成成功，则将链接显示在屏幕上。

   ElevatedButton(
     onPressed: _generateReferralLink,
     child: const Text('Generate Referral Link'),
   ),
   if (_referralLink != null)
     Padding(
       padding: const EdgeInsets.all(8.0),
       child: Text(
         'Your referral link: $_referralLink',
         style: TextStyle(fontSize: 16),
       ),
     ),
