E / flutter（17744）：[错误：flutter / lib / ui / ui_dart_state.cc（148）]未处理的异常：无效的响应行

Question

我正在使用http.post（）发出http发布请求。 我在回应中遇到以下错误。 以下是我面临错误的代码：

import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:mysqltest/util/user_credentials.dart';
import 'package:dbcrypt/dbcrypt.dart';
Future<List> fetchAuthenticatedUser(UserCredentials credentials) async {
  final response =
      await http.post('http://10.0.2.2:5554/fluttertest/login.php',
      body: {
    "email": credentials.getEmail,
    "password":
      new DBCrypt().hashpw(credentials.getPassword, new DBCrypt().gensalt())
    }
  );

  if (response.statusCode >= 200) {
    try {
      for(var user in json.decode(response.body)) {
          var isCorrect = new DBCrypt().checkpw(
              credentials.getPassword, user['password']);
          if (isCorrect){
          return json.decode(response.body);}

         }

    } catch (e) {
       print(e);
      return [];
    }
  }
  return [];
}
