How to make Gridview list clikable when i click. i try to use InkWell inside gridview like this. but, it doesn't work. does anyone have a solution?

Container(
  child: GridView.count(
    mainAxisSpacing: 10,
    scrollDirection: Axis.vertical,
    shrinkWrap: true,
    crossAxisCount: 4,
    children: List.generate(ppobList.length, (index) {
      return InkWell(
        onTap: () {
          print("tab ppob");
        },
        child: PpobItem(
            title: ppobList[index].name,
            icon: ppobList[index].icon),
      );
    }),
  ),
);

class PpobItem extends StatelessWidget {
  const PpobItem({
        Key? key,
        required this.title,
        required this.icon,
      }) : super(key: key);

  final String title;
