参考https://www.jianshu.com/p/05dab8542233

GridView(
        shrinkWrap: true,
        physics: NeverScrollableScrollPhysics(),
        gridDelegate: SliverGridDelegateWithMaxCrossAxisExtent(
          maxCrossAxisExtent: 72,
          crossAxisSpacing: 10,
          mainAxisSpacing: 10,
          childAspectRatio: 72 / 34,
        ),
        children: [
          SizedBox(height:34)
        ],
      )
