I just started flutter. I tried to make a card structure but I think it is quite wrong. I could never fix it. I am using Gridview extend. In this way, the column numbers change dynamically as the screen gets smaller or larger. but i keep getting overflow error what should i do.

 var response = sepet.itemsCount[item.name];
 return SizedBox(
   child: Padding(
     padding: EdgeInsets.all(0),
     child: Column(
       crossAxisAlignment: CrossAxisAlignment.stretch,
       children: [
         Card(
           shape: RoundedRectangleBorder(
               borderRadius: BorderRadius.all(Radius.circular(8.0))),
           child: InkWell(
             customBorder: RoundedRectangleBorder(
               borderRadius: BorderRadius.circular(8),
             ),
             onTap: () {},
             child: Column(
               children: <Widget>[
                 ListTile(
                   title: Text(item.name ?? ''),
                   subtitle: Text(item.defaultPrice.toString()   '\$'),
                 ),
                 Padding(
                   padding: EdgeInsets.all(8.0),
                   child: Row(
                     mainAxisAlignment: MainAxisAlignment.spaceAround,
                     children: [
                       Row(
                         mainAxisAlignment: MainAxisAlignment.spaceAround,
                         children: <Widget>[
                           countChanger(sepet, false, item),
                           Padding(
                             padding: EdgeInsets.only(left: 8.0, right: 8.0),
                             child: Text(
                               response != null ? response.toString() : '0',
                               style: TextStyle(fontSize: 18.0),
                             ),
                           ),
                           countChanger(sepet, true, item),
                         ],
                       ),
                       ButtonTheme(
                         height: 25,
                         minWidth: 25,
                         child: ElevatedButton(
                           onPressed: () {
                             !isAdded
                                 ? sepet.sepeteEkle(item)
                                 : sepet.deleteItem(item);
                           },
                           style: ElevatedButton.styleFrom(
                             primary: !isAdded
                                 ? Colors.teal
                                 : Colors.red,
                           ),
                           child: Text(!isAdded ? 'Ekle' : 'Çıkar'),
                         ),
                       ),
                     ],
                   ),
                 )
               ],
             ),
           ),
         ),
       ],
     ),
   ),
 ); 

My gridview extend structure is like this

child: GridView.extent(
        physics: NeverScrollableScrollPhysics(),
        shrinkWrap: true,
        maxCrossAxisExtent: 250.0,
        crossAxisSpacing: 20.0,
        mainAxisSpacing: 20.0,
        children: List.generate(foods!.length, (index) {
          return itemCard(foods[index].menuItem ?? MenuItem(), value);
        }),

The question you need to answer is what would you like to happen if the width of that card is so small? Do you want a different arrangement of those elements? If you do decide on what that would look like and check the constraint with LayoutBuilder Or the whole screen width with MediaQuery whatever you feel is best. You could also make that bit scroll horizontally by using SingleChildScrollView. This is a design decision. You must image what things look like when screen size changes, and be as deliberate as possible with the responsiveness rather then to just try to find some magic widget which we are all guilty of doing sometimes.
