颤振-设置列表图块高度

我正在尝试创建动态水平列表视图。但是,当我创建列表视图时,它将占据页面上的剩余垂直空间。我尝试使用容器来限制高度,但没有成功。到目前为止,这是我尝试过的:

列出图块...

  class CardTile extends StatelessWidget {

  final GreetingCard greetingCard;

  const CardTile({Key key, this.greetingCard}) : super(key: key);


  @override
  Widget build(BuildContext context) {
    return
      Container(
        height: 150.0,
        width: 80.0,
        child: Card(
          child: ListTile(
            title: Center(child: Text(greetingCard.ocassion)),
          ),
        ),
      );
  }
}

列表视图生成器:

  class CardList extends StatefulWidget {
  @override
  _CardListState createState() => _CardListState();
}

class _CardListState extends State<CardList> {
  @override
  Widget build(BuildContext context) {

    final greetingsCards = Provider.of<List<GreetingCard>>(context);

    return ListView.builder(
        itemCount: greetingsCards.length,
        itemBuilder: (context, index){
        return Card(
            child: CardTile(greetingCard: greetingsCards[index],));
      }, scrollDirection: Axis.horizontal);
  }
}

如何将高度限制为150像素?

您需要限制ListView.builder的高度:

Container(
  height: 150.0,
  child: ListView.builder(
    ...
  ),
)
