id is not retreived onTap from ListView.builder flutter

Question

I am having trouble retrieving the id of a card on tapping. The card is the outlet card, retrieved from the firestore via streambuilder. Cards appear with no issues. However, when I tap on it the outletId value returns null. Also, debugPrint() prints nothing to console. What am I doing wrong? Thank you in advance!

 StreamBuilder(
stream: FirebaseFirestore.instance.collection('users')
    .where(widget.orderModel.type!, isEqualTo: true)
    .snapshots()
    .map(
(snapshot) => snapshot.docs
    .map((document) => OutletModel.fromJson(document.data()))
    .toList()),
builder: (_, AsyncSnapshot snaps) {
  if (!snaps.hasData) {
    return Center(
        child: Text(Languages.of(_)!.noData));
  } else {
    return ListView.builder(
        physics: const ScrollPhysics(),
        scrollDirection: Axis.vertical,
        shrinkWrap: true,
        itemCount: snaps.data.length,
        itemBuilder: (BuildContext context, int index) {
          return InkWell(
onTap: () async {
            selected == false ?
            setState(() {
              selected = true;

              outletId = snaps.data[index]['id'];
              widget.orderModel.shopId =
              snaps.data[index]['id'];
              outletName = snaps.data[index]['outletName'];
              emailS = snaps.data[index]['email'];
              phoneN = snaps.data[index]['phoneNumber'];
              widget.orderModel.customerPet =
                  widget.petModel.id;

              debugPrint(
                  'the shopId is =======> ${snaps.data[index]['id']}');
            })
            : setState((){
              selected = false;
            });
          }
          child:  selected == true ? 
Stack(
              children: [
          OutletCard(outletModel: snaps.data[index]),
                const Positioned(
                        right: 0,
          top: 0,
          child: Icon(
          Icons.check_circle_outline, color: Colors.green,
          size: 50)
          ),

          ],
          ) : OutletCard(outletModel: snaps.data[index]);  
          );     
        });
  }
}
),

and the outlet card's widget is

@override

SizeConfig().init(context);

double screenWidth = SizeConfig.safeBlockHorizontal! * 100;
