dart - 如何将图像适合作为容器小部件的背景图像？

Question

我正在尝试创建类别卡，并将图像设置为子容器小部件的背景，但是图像未显示在容器上

Container job1category(String imgpath, String name, String nikename) {
return Container(
width: 170,    
child: Card(
  child: Wrap(
    children: <Widget>[
      Container(
        decoration: BoxDecoration(
          image: DecorationImage(
            image: AssetImage(imgpath),
            fit: BoxFit.cover
          )
        ),
        child: null
      ),
      ListTile(
        title: Text(name),
        subtitle: Text(nikename),
      ),
    ],
  ),
),
);
}
