以下是一个完整的示例代码，展示了如何使用flutter_xfyun_ise插件进行语音测评。

import 'package:flutter/material.dart';
import 'package:flutter_xfyun_ise/bean/ise_param.dart';
import 'package:flutter_xfyun_ise/flutter_xfyun_ise.dart';

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

class _MyAppState extends State<MyApp> {
  /// 测试内容文本
  var content = "一座座雪峰插入云霄，峰顶银光闪闪，大大小小的湖泊，像颗颗宝石镶嵌在彩带般的沟谷中。";
  var _score = "暂无评分";
  var _path = "";

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

  // 设置监听处理
  void setListener() {
    FlutterXfyunIse.instance.setOnErrorListener((error) {
      print("****************************");
      print("错误信息：    ${error}");
      print("****************************");
    });
    FlutterXfyunIse.instance.setOnResultListener((score) {

      print("回调信息：    ${score["total_score"]}");
      print("回调信息：    ${score["phone_score"]}");
      Map map = score["phone_score"];
      map.forEach((key, value) {
        print("key:     $key    -----       value:       $value");
      });
      // setState(() {
