我一直在尝试在博客中弹出博客文章，但每次运行该应用程序时，都不会弹出任何东西。我尝试将Card对象放入onTap语句中。
代码如下：
article_view.dart
import 'package:flutter/material.dart';
import 'package:scip_app/articles_data.dart';
class _ArticleListItem extends ListTile {
_ArticleListItem(Article article) :
super(
title: new Text(article.title),
subtitle: new Text(article.blurb),
onTap: () {
new FullArticleDisplay(article);
}
);
}
class FullArticleDisplay extends StatelessWidget {
final Article article;
FullArticleDisplay(this.article);
@override
Widget build(BuildContext context) {
return new Container(
child: new Card(
child: new Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
new ListTile(
title: new Text(article.title),
),
new Text(article.articled),
]
)
)
);
}
}
class ArticleList extends StatelessWidget {
final List<Article> _articles;
ArticleList(this._articles); …我查看了我的代码几次并查看了此错误的所有先前答案，但仍然找不到解决方案。
下面是有问题的代码：
