I have done minor modification to show it as a grid. Though if it is not as per you, please share the design you want to achieve.

GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: MediaQuery.of(context).orientation ==
              Orientation.landscape ? 3: 2,
          crossAxisSpacing: 8,
          mainAxisSpacing: 8,
        )
        itemCount:model.isGettingCategories ? 5 : model.categories.length,
        shrinkWrap: true,
        itemBuilder: (_,index,)  => model.isGettingCategories
            ? _catLoadingItem()
            : _catItem(model.categories[index]),
      )
