Flutter Can'；t初始化Back4App的解析服务器。不断获得<；异步悬挂>；

在尝试连接到parse（Back4App）服务器时，我一直处于异步暂停状态。我的代码如下。在将parse_server_sdk_flatter:2.1.0添加到pubspec.yaml后，我得到了冲突的包。因此，我将这些冲突包的版本更改为ANY。我什么都试过了，请帮忙

import 'package:flutter/material.dart';    
import 'package:hive/hive.dart';
import 'package:hive_flutter/hive_flutter.dart';
import 'package:path_provider/path_provider.dart';
import 'package:parse_server_sdk_flutter/parse_server_sdk.dart';

void main() async{
      WidgetsFlutterBinding.ensureInitialized();
      final appDocDir = await getApplicationDocumentsDirectory();
      /// HIVE STARTS
      await Hive.initFlutter(appDocDir.path);
      await Hive.openBox("Name");
      await Hive.openBox("Type");
      await Hive.openBox("Added");
      await Hive.openBox("Notes");
      /// HIVE ENDS

      /// BACK4APP STARTS
    
      final keyApplicationId = 'XRLZJug8U5VghiklDHLDlGMiChkRsSMYg6O34ZRi';
      final keyClientKey = 'd1WBVMdAhbk32V4S4rCc5YfZnuH0DUPTQbWnbtqD';
      final keyParseServerUrl = 'https://parseapi.back4app.com/';
     await Parse().initialize(keyApplicationId, keyParseServerUrl,
          clientKey: keyClientKey, debug: true);
    
      await Parse().initialize(keyApplicationId, keyParseServerUrl,
          clientKey: keyClientKey, autoSendSessionId: true);
    
      /// test
      var firstObject = ParseObject('FirstClass')
        ..set(
            'message', 'Hey ! First message from Flutter. Parse is now connected');
      await firstObject.save();
    
      print('IT IS WORKING');
    
      /// BACK4APP ENDS
      runApp(MyApp());
    }

错误消息位于下面：

路径：packages/flatter

不幸的是，解析flatter sdk对于flatter 2.0还不能很好地工作。正在最终确定解决方案，您可以在此线程中跟踪更新：。同时，您需要使用Flatter1.22或不使用任何其他迁移包。谢谢您提供的信息。
