我会滚动全屏幕图像在Flutter，但我有一个问题，当我使用BoxDecoration内ListView

ListView(
  scrollDirection: Axis.horizontal,
  children: <Widget>[
    Container(
      decoration: BoxDecoration(
        image: DecorationImage(
          image: AssetImage('assets/fav.JPG'),
          fit: BoxFit.fitHeight,
        ),
      ),
    ),
    Container(
      decoration: BoxDecoration(
        image: DecorationImage(
          image: AssetImage('assets/fav.JPG'),
          fit: BoxFit.fitHeight,
        ),
      ),
    ),
  ],
)

实际上我收到的是一张空白页。我们的想法是做一些像Netflix通过点击“预览”。
谢谢
