Answer 2

要修改卡片的宽度或高度，可以将其包装在Container Widget中，并为其提供height和/或width属性。

请在下面的代码中看到一个用高度为500的容器包装的容器：

    Container(
      height: 500,
      child: Card(
        semanticContainer: true,
        clipBehavior: Clip.antiAliasWithSaveLayer,
        child: Image.network(
          'https://placeimg.com/640/480/any', fit: BoxFit.fill,),
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(10.0),
        ),
        elevation: 5,
        margin: EdgeInsets.all(10),
      ),
    ),
