Flutter用户推荐系统插件referralhero的使用

Flutter用户推荐系统插件referralhero的使用

referralhero 是一个用于 Flutter 应用的推荐系统插件。通过这个插件，您可以轻松地集成推荐功能到您的应用中。

开始使用

这个项目是一个 Flutter 插件包的起点，该插件包包含针对 Android 和/或 iOS 的平台特定实现代码。

对于 Flutter 开发的帮助，可以查看 官方文档，其中包括教程、示例、移动开发指南以及完整的 API 参考。

示例代码

以下是使用 referralhero 插件的基本示例代码：

import 'dart:convert';

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

import 'package:flutter/services.dart';
import 'package:referralhero/referralhero.dart';
import 'package:referralhero_example/zip_code_details.dart'; // 假设这是从外部库导入的

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

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

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  final _referralheroPlugin = Referralhero(); // 初始化插件实例
  String zipCode = '33162';
  Map<String, dynamic>? zipCodeDetails = null;

  // 获取邮政编码详情
  Future<void> getZipCodeDetails() async {
    try {
      final value = await _referralheroPlugin.getZipCodeDetails(zipCode)!;
      print('Received details: $value'); // 调试打印语句
      if (!mounted) return;
      setState(() {
        zipCodeDetails = jsonDecode(value);
        print('Country details: ${zipCodeDetails}');
      });
    } catch (e) {
      print('Error retrieving zip code details: $e');
    }
  }

  // 初始化插件状态
  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
    getZipCodeDetails();
  }

  // 异步初始化插件
  Future<void> initPlatformState() async {
    String platformVersion;
    // 处理平台消息可能失败的情况
    try {
      platformVersion =
          await _referralheroPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    String? raw = await _referralheroPlugin.initializeSdk("Jaspalsinh", "Gohil"); // 初始化SDK
    print("object {$raw}");

    // 如果组件在异步平台消息处理期间被移除，则丢弃回复
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  // 构建UI
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('插件示例应用'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              ElevatedButton(
                onPressed: getZipCodeDetails,
                child: Text('获取邮政编码详情'),
              ),
              SizedBox(height: 16),
              if (zipCodeDetails != null) // 检查是否不为空再访问元素
                Column(
                  children: [
                    Text('邮政编码: ${zipCodeDetails?["post code"]}'),
                    Text('国家: ${zipCodeDetails?["country"]}'),
                    Text('州: ${zipCodeDetails?["places"][0]["state"]}'),
                    Text('城市: ${zipCodeDetails?["places"][0]["place name"]}'),
                  ],
                ),
            ],
          ),
        ),
      ),
    );
  }
}

代码解释

1. 导入必要的包：

   import 'package:flutter/material.dart';
   import 'package:flutter/services.dart';
   import 'package:referralhero/referralhero.dart';
   

2. 初始化应用：

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

3. 定义主应用类：

   class MyApp extends StatefulWidget {
     const MyApp({super.key});
   
     [@override](/user/override)
     State<MyApp> createState() => _MyAppState();
   }
   

4. 定义状态类：

   class _MyAppState extends State<MyApp> {
     String _platformVersion = 'Unknown';
     final _referralheroPlugin = Referralhero();
     String zipCode = '33162';
     Map<String, dynamic>? zipCodeDetails = null;
   

5. 获取邮政编码详情的方法：

   Future<void> getZipCodeDetails() async {
     try {
       final value = await _referralheroPlugin.getZipCodeDetails(zipCode)!;
       print('Received details: $value'); // 调试打印语句
       if (!mounted) return;
       setState(() {
         zipCodeDetails = jsonDecode(value);
         print('Country details: ${zipCodeDetails}');
       });
     } catch (e) {
       print('Error retrieving zip code details: $e');
     }
   }
   

6. 初始化插件状态：

   [@override](/user/override)
   void initState() {
     super.initState();
     initPlatformState();
     getZipCodeDetails();
   }
   

7. 异步初始化插件：

   Future<void> initPlatformState() async {
     String platformVersion;
     try {
       platformVersion =
           await _referralheroPlugin.getPlatformVersion() ?? 'Unknown platform version';
     } on PlatformException {
       platformVersion = 'Failed to get platform version.';
     }
   
     String? raw = await _referralheroPlugin.initializeSdk("Jaspalsinh", "Gohil");
     print("object {$raw}");
   
     if (!mounted) return;
   
     setState(() {
       _platformVersion = platformVersion;
     });
   }
   

8. 构建UI：

   [@override](/user/override)
   Widget build(BuildContext context) {
     return MaterialApp(
       home: Scaffold(
         appBar: AppBar(
           title: const Text('插件示例应用'),
         ),
         body: Center(
           child: Column(
             mainAxisAlignment: MainAxisAlignment.center,
             children: [
               ElevatedButton(
                 onPressed: getZipCodeDetails,
                 child: Text('获取邮政编码详情'),
               ),
               SizedBox(height: 16),
               if (zipCodeDetails != null)
                 Column(
                   children: [
                     Text('邮政编码: ${zipCodeDetails?["post code"]}'),
                     Text('国家: ${zipCodeDetails?["country"]}'),
                     Text('州: ${zipCodeDetails?["places"][0]["state"]}'),
                     Text('城市: ${zipCodeDetails?["places"][0]["place name"]}'),
                   ],
                 ),
             ],
           ),
         ),
       ),
     );
   }
