Flutter：ListView实现一个可左右滑动的商品列表

// 爆款商品
Widget _buildFlashSell() {
  return <Widget>[
    SizedBox(height: 25.w,),
    // 标题
    <Widget>[
      TDImage(assetUrl: "assets/myimage/nav-11.png",width: 36.w,height: 36.w,),
      SizedBox(width: 7.w,),
      TextWidget.body('爆款商品',size: 28.sp,color: const Color(0xff181818),),
      SizedBox(width: 20.w,),
      TextWidget.body('品质卓越，超值享受，一切尽在我们的爆款产品！ ',size: 20.sp,color: const Color(0xff999999),),
    ].toRow(
      crossAxisAlignment: CrossAxisAlignment.baseline,
      textBaseline: TextBaseline.alphabetic,
    ).paddingHorizontal(30.w),
    SizedBox(height: 30.w,),

    // 爆款商品可左右滑动查看
    <Widget>[
      SizedBox(width: 30.w,),
      for (var i = 0; i < 5; i++)
      <Widget>[
        TDImage(assetUrl: "assets/myimage/goods.png",width: 200.w,height: 160.w,),
        SizedBox(height: 5.w,),
        TextWidget.body(
          '爆款商品爆款商品爆款商品',
          size: 28.sp,
          color: const Color(0xff181818),
          overflow: TextOverflow.ellipsis,
          maxLines: 1,
        ),
        SizedBox(height: 5.w,),
        <Widget>[
          TextWidget.body('￥',size: 24.sp,color: const Color(0xffFF6E00),),
          TextWidget.body('599.00',size: 28.sp,color: const Color(0xffFF6E00),),
        ].toRow(),
        Text('原价￥599.00',

            decorationColor: const Color(0xff999999)
          ),
        ),
      ].toColumn(crossAxisAlignment: CrossAxisAlignment.start).width(200.w).marginOnly(right: 15.w),
      SizedBox(width: 15.w,),
    ].toListView(scrollDirection: Axis.horizontal,).expanded(),

  ].toColumn()
  .decorated(border: Border.all(width: 1, color: const Color(0xffEDF1F2)),borderRadius: BorderRadius.circular(20.w))
  .tight(height: 390.w);
