}

关键部分

GridView.builder(physics: const NeverScrollableScrollPhysics(),shrinkWrap: true,itemCount: 10,gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(//横轴元素个数crossAxisCount: 2,//纵轴间距mainAxisSpacing: 15.r,//横轴间距crossAxisSpacing: 15.r,//子组件宽高长度比例childAspectRatio: 165 / 105,),itemBuilder: (_, position) {KLogUtil.d(position);return _pastGrantsListItem(position / 2 == 0);});}

其中physics属性  physics: const NeverScrollableScrollPhysics()会禁止页面滚动

shrinkWrap 让容器被内容撑满
