dart - Flutter draggable widget not showing feedback in iPhone 15 - Stack Overflow

I recently noticed an issue on iPhone 15. I have a word game built in Flutter web, in which the user has to drag and drop tiles to match words with synonyms. For this I have used a draggable widget with feedback as seen in the code below.

return Stack(
  children: [
    (wordList.colors[index] != wordList.green)
        ? DragTarget<Map>(
            hitTestBehavior: HitTestBehavior.translucent,
            builder: ((context, candidateData, rejectedData) {
              return Draggable<Map>(
                  rootOverlay: true,
                  onDragStarted: () {
                    lIndex = index;
                  },
                  data: {'text': str, 'index': index},
                  feedback: ClipRRect(
                    borderRadius: BorderRadius.circular(12.0),
                    child: Card(
                      elevation: 5,
                      shadowColor: Colors.grey,
                      child: Container(
                        color: Colors.grey.shade200,
                        child: Text(
                          str,
                          style: const TextStyle(
                              fontSize: 18, color: Colors.black87),
                        ),
                      ),
                    ),
                  ),
                  childWhenDragging: Container(
                    width: 50,
                    height: 20,
                    color: Colors.grey,
                  ),
                  child: ClipRRect(
                    borderRadius: BorderRadius.circular(12.0),
                    child: Card(
                      elevation: 10,
                      shadowColor: Colors.grey,
                      child: Container(
                          padding: const EdgeInsets.symmetric(
                              horizontal: 12.0, vertical: 2.0),
                          // margin: const EdgeInsets.symmetric(vertical: 6.0),
                          decoration: BoxDecoration(
                            border: Border.all(color: Colors.black38),
                            borderRadius: BorderRadius.circular(12.0),
                            color: wordList.colors[index],
                          ),
                          child: FittedBox(
                            child: Text(
                              str,
                              style: const TextStyle(fontSize: 20),
                              maxLines: 1,
                            ),
                          )),
                    ),
                  ));
            }),
            onWillAcceptWithDetails: (data) {
              return true;
            },
            onAcceptWithDetails: (value) {
              swapWords(value.data, index);
              refresh();
            },
          )

This works perfectly on Android phones, desktops and even iPhones prior to 15 on Safari browser. I dont know what has changed in the new iPhones that the feedback widget is not seen at all. As a result when the user drags and drops a word tile, the words swap alright but there is no indication to the user that he has dragged something.

You can see the game behavior at / Play it on iPhone 15 and on any other device and see the difference.

Any help / pointers would be appreciated.
