The rest of this course would focus on building a news reader app. In this episode, we’ll combine what we’ve learnt so far to build an article card widget. I’ve cleared out the previous code in the MainPage widget and the body currently returns an ArticleCard widget.

...
  final Article article;

  const ArticleCard({
    Key? key,
    required this.article,
  }) : super(key: key);
...

ArticleCard(article: articles[0])

...
return Card(
  margin: const EdgeInsets.all(16),
  elevation: 4,
  child: Column(
    children: <Widget>[
      CardBanner(),
      CardDetail(),
    ]
  ),
);
...

class CardDetail extends StatelessWidget {
  final Article? article;

  const CardDetail({Key? key, this.article}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(16),
      child: Column(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          Text(
            article!.title,
            style: const TextStyle(fontSize: 24),
            maxLines: 2,
            overflow: TextOverflow.ellipsis,
          ),
          const SizedBox(height: 16),
          Row(
            children: <Widget>[
              Text(article!.source),
              const Spacer(),
              const Text('45 Comments'),
            ],
          )
        ],
      ),
    );
  }
}

...
CardDetail(article: article),
...

class CardBanner extends StatelessWidget {
  final String? imageUrl;

  const CardBanner({Key? key, this.imageUrl}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const Placeholder(fallbackHeight: 200);
  }
}

...
Stack(
  children: [
    const Placeholder(
      fallbackHeight: 200,
    ),
    Positioned(
      top: 10,
      right: 10,
      child: IconButton(
        icon: const Icon(Icons.bookmark_border, size: 32),
        onPressed: (){},
      ),
    ),
  ],
),
