Container(
  height: 200.0,
  padding: EdgeInsets.symmetric(vertical: 20.0, horizontal: 10.0),

      padding: EdgeInsets.only(right: 8.0),
      scrollDirection: Axis.horizontal,
      itemBuilder: (context, index) {
        FoodCate foodCate = snap.data[index];
        return FoodKindButton(img: foodCate.img, title: foodCate.cate);
      },
      separatorBuilder: (context, index) {
        return Container(
          color: Colors.transparent,
          width: 1.0,
        );
      },
      itemCount: snap.data.length),
);
