SizedBox(
width: w-80,
height: h-80,
child: ListView.builder(
itemCount: h~/10 - 8,
padding: EdgeInsets.zero,
physics: const NeverScrollableScrollPhysics(),
shrinkWrap: true,
itemBuilder: (context,index){
return SizedBox(
height: h/10 - 8,
child: ListView.builder(
itemCount:w~/10 - 8,
padding: EdgeInsets.zero,
