Flutter http.dart POST Ordered list

[kujaomega]

When making an HTTP POST, the lists are loosing the order. This is the case:

import 'dart:async';
import 'dart:convert';
import 'package:http/http.dart' as http;

class MatchClient {
  final String baseUrl;
  final http.Client httpClient;

  MatchClient({
    http.Client httpClient,
    this.baseUrl = 'http://192.168.1.1:8080/match',
}) : this.httpClient = httpClient ?? http.Client();

  Future<QuarterResult> compute(QuarterMatch quarterMatch) async {
    // At this point, the order is maintained
    final body = jsonEncode(quarterMatch);
    // When I make the post, the list inside the object, loose the order
    final response = await httpClient.post(
        Uri.http(baseUrl, '/match'),
        headers: {
          'Content-Type': 'application/json',
        },
        body: body);
    // In the browser the http request is shooted with a disordered list
    final dynamic results = json.decode(response.body);
  }
}

Issue solved, server issue
