错误：在我的应用程序中，错误地使用了ParentDataWidget。

我正在使用Flutter制作一家报纸网站，但是每当我打开一个新闻项目时，就会出现以下错误：“Incorrect use of ParentDataWidget.”，有人知道如何解决吗？\n通知列表：\nclass ArticlesPosts {\n String title;\n String titleHome;\n String subtitle;\n String pic;\n String author;\n String notice;\n String data;\n ArticlesPosts({\n this.title,\n this.titleHome,\n this.subtitle,\n this.author,\n this.pic,\n this.notice,\n this.data,\n });\n}\nvar allPosts = [\n ArticlesPosts(\n title:\n \'XXXXXXX\',\n titleHome: \'XXXXXXXXXXXXX\',\n subtitle: \'sssssssssssssssssssssssssssssssssssssssssssssss\',\n author: \'nome\',\n pic: \'assets/1.jpg\',\n notice:\n \'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\',\n data: \'Published in 14/04/2021\',\n ),\n];\n\n主页新闻页面：\nimport \'package:flutter/material.dart\';\nimport \'package:flutter_application_1/views/home/posts.dart\';\nimport \'articlesDetails.dart\';\nclass MainScreen extends StatelessWidget {\n final posts = allPosts;\n @override\n Widget build(BuildContext context) {\n return ListView(\n children: [\n Column(children: [\n SizedBox(height: 20),\n Padding(\n padding: EdgeInsets.only(left: 15.0),\n child: Text(\n \"RobSIC News\",\n style: TextStyle(\n fontWeight: FontWeight.w800, height: 3.0, fontSize: 26),\n ),\n ),\n SizedBox(height: 30),\n Container(\n height: MediaQuery.of(context).size.height -
