项目中有实名认证的需求，用户上传身份证反正面，进行人脸核验，后台集成的是阿里云的金融级实名认证SDK，巧合的是阿里云没有packages 需要自己造轮子。
废话不多少，直接上代码：

新建项目 ProjectType = Plugin

创建完成后，会自动为我们搭建好通信结构

编写Dart中间件

在项目下的 lib下的dart文件中定义我们的通信方法。
实名认证 需要两个方法 分别是：
获取本机信息发送给服务器 返回ID
调用实名认证，以及返回结果

import 'dart:async'; import 'package:flutter/services.dart'; class AliAuthPerson { static const MethodChannel _channel = MethodChannel('ali_auth_person'); static Future<String?> get platformVersion async { final String? version = await _channel.invokeMethod('getPlatformVersion'); return version; } static const EventChannel _eventChannel = EventChannel("ali_auth_person_plugin_event"); ///认证结果返回监听 static addListen(Function(String resData) onEvent) { _eventChannel.receiveBroadcastStream().listen((data) { onEvent(data); }); } ///实名认证 static Future<void> verify(String certifyId) async { await _channel.invokeMethod("verify", certifyId); } ///获取本机参数 static Future<String> getMetaInfos() async { return await _channel.invokeMethod("getMetaInfos"); } }
