Flutter/Dart解析网站图片失败，仅获取到占位图而非真实URL

我在解析arbuz.kz网站数据时，标题、价格等内容都能正常抓取，但商品图片始终只能拿到占位图路径/static/platform/frontend/assets/app/image-placeholder.svg，尝试解析其他电商网站也遇到同样的情况。

以下是我的Flutter代码：

import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'package:html/dom.dart' as dom;
import 'package:xleb/data/article.dart';

class MainPage extends StatefulWidget {
  const MainPage({super.key});

  @override
  State<MainPage> createState() => _MainPageState();
}

class _MainPageState extends State<MainPage> {
  List<Article> articles = [];

  @override
  void initState() {
    getWebsiteData();

    super.initState();
  }

  Future getWebsiteData() async {
    final url = Uri.parse(
        'https://arbuz.kz/ru/collections/249615-pozabottes_o_sebe_#/');
    final response = await http.get(url);
    dom.Document html = dom.Document.html(response.body);

    final titles = html
        .querySelectorAll(' article > main > a')
        .map((e) => e.innerHtml.trim())
        .toList();
    final prices =
        html.querySelectorAll('b').map((e) => e.innerHtml.trim()).toList();

    final urlImages =
        html.querySelectorAll('img').map((e) => e.attributes['src']!).toList();
    print(urlImages);
    print(titles);

    setState(() {
      articles = List.generate(
        titles.length,
        (index) => Article(
          title: titles[index],
          price: prices[index],
          urlImage: urlImages[index],
        ),
      );
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(),
        body: ListView.builder(
            itemCount: articles.length,
            itemBuilder: (context, index) {
              final article = articles[index];
              return ListTile(
                title: Text(article.title),
                subtitle: Text(article.price),
                leading:
                    SizedBox(width: 50, child: Image.network(article.urlImage)),
              );
            }));
  }
}
