Question

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),
)

Answer 1

要修改卡片的宽度或高度，您可以将其包装在 Container Widget 中并为其提供高度和/或宽度属性。

请参阅下面的代码，该代码使用高度为 500 的容器包装：

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),
  ),
),
