Not able to tap on Card

[utsavDave97]

I have the following code to group items based on whether they have been routed or not

GroupedListView<Parcels, int>(
        elements: snapshot.data,
        groupBy: (element) => element.isRouted ? 1 : -1,
        itemComparator: (p1, p2) => p1.isRouted == p2.isRouted ? 1 : -1,
        groupHeaderBuilder: (Parcels p) {
          return Container(
            padding: const EdgeInsets.all(20),
            child: Text(
              p.isRouted ? 'Parcels optimized' : 'Parcels not optimized',
              style: TextStyle(color: Colors.black),
            ),
          );
        },
        itemBuilder: (c, element) {
          return ParcelCard( //code for this is below
            parcel: element,
            listType: listType,
          );
        },
      )

It does display items into groups but not able to tap on them.

Card(
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(8.0),
      ),
      elevation: 3,
      margin: EdgeInsets.symmetric(vertical: 1.0.h, horizontal: 2.0.w),
      color: Colors.white,
      child: InkWell(
        onTap: () {
          showBottom(context, parcel,listType); //THIS ONTAP DOESN'T WORK
        },
        child: Container(
          height: 13.0.h,
          width: 100.0.w,
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceAround,
            children: [....
              ......
             ........

Any reason why?

Appreciate your library.
