RefreshIndicator 不能与 GridView 一起使用，因为 GridView 需要物理：ScrollPhyscis()&refreshindicator 需要 AlwaysScrollablePhysics() 才能出现

GetBuilder<StateController>(builder: (value) {
                        return RefreshIndicator(
                          onRefresh: refresh,
                          child: GridView.builder(
                              physics: ScrollPhysics(),
                              itemCount:
                                  _offerCashbackCont.mdlOffers.data.length,
                              shrinkWrap: true,
                              padding: EdgeInsets.all(10),

将 GridView 放在 SingleChildScrollView 中就足够了，将一组 GridView 物理设置为 NeverScrollable

return RefreshIndicator(
  onRefresh: refresh,
  child: SingleChildScrollView(
    child: GridView.builder(
      physics: const NeverScrollableScrollPhysics(),
      itemCount:
          _offerCashbackCont.mdlOffers.data.length,
      shrinkWrap: true,
      padding: EdgeInsets.all(10),
      gridDelegate:
          SliverGridDelegateWithFixedCrossAxisCount(
              crossAxisCount: 2,
              mainAxisSpacing: 10.0,
              crossAxisSpacing: 10.0,
              childAspectRatio: 0.7),
      itemBuilder: (context, index) {
        return SingleProduct(...
