項目中有實名認證的需求，用戶上傳身份證反正面扛门，進行人臉核驗沐祷，后臺集成的是阿里云的金融級實名認證SDK嚷闭，巧合的是阿里云沒有packages 需要自己造輪子。
廢話不多少赖临，直接上代碼：

新建項目 ProjectType = Plugin

創(chuàng)建完成后胞锰，會自動為我們搭建好通信結(jié)構(gòu)

編寫Dart中間件

在項目下的 lib下的dart文件中定義我們的通信方法。
實名認證 需要兩個方法 分別是：
獲取本機信息發(fā)送給服務(wù)器 返回ID
調(diào)用實名認證兢榨，以及返回結(jié)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");

  ///認證結(jié)果返回監(jiān)聽
  static addListen(Function(String resData) onEvent) {
    _eventChannel.receiveBroadcastStream().listen((data) {
      onEvent(data);
    });
  }

  ///實名認證
  static Future<void> verify(String certifyId) async {
    await _channel.invokeMethod("verify", certifyId);
  }

  ///獲取本機參數(shù)
  static Future<String> getMetaInfos() async {
    return await _channel.invokeMethod("getMetaInfos");
  }
}
