is it possible to capture the BottomNavigationBarItem double click event in flutter-CodePudding

I am capture the double click in flutter navigate button using GestureDetector like this way:

return Scaffold(
      body: viewService.buildComponent("homelist"),
      bottomNavigationBar: GestureDetector(
        onDoubleTap: () {
          _onItemDoubleTapped();
        },
        child: BottomNavigationBar(
            items: [
              BottomNavigationBarItem(icon: Icon(Icons.home), label: AppLocalizations.of(context)!.cruiseNavigatorHome),
              BottomNavigationBarItem(icon: Icon(Icons.subscriptions), label: AppLocalizations.of(context)!.cruiseNavigatorSubscribe),
              BottomNavigationBarItem(icon: Icon(Icons.rss_feed), label: AppLocalizations.of(context)!.cruiseNavigatorChannel),
              BottomNavigationBarItem(icon: Icon(Icons.school), label: AppLocalizations.of(context)!.cruiseNavigatorMine),
            ],
            currentIndex: state.selectIndex,
            fixedColor: Theme.of(context).primaryColor,
            onTap: _onItemTapped,
            unselectedItemColor: Color(0xff666666),
            type: BottomNavigationBarType.fixed),
      ));

double click item trigger _onItemDoubleTapped event works fine, but now I want to capture the double click of each navigator item. Is it possible to capture the double click event in flutter? I have also tried like this way:

return Scaffold(
    body: viewService.buildComponent("homelist"),
    bottomNavigationBar: BottomNavigationBar(
        items: [
          BottomNavigationBarItem(
              icon: InkWell(
                  onDoubleTap: () {
                    _onItemDoubleTapped();
                  },
                  child: Icon(Icons.home)),
              label: AppLocalizations.of(context)!.cruiseNavigatorHome),
          BottomNavigationBarItem(
              icon: InkWell(
                  onDoubleTap: () {
                    final SubListDefaultController subListDefaultController = Get.put(SubListDefaultController());
                    subListDefaultController.isScrollTop = true;
                  },
                  child: Icon(Icons.subscriptions)),
              label: AppLocalizations.of(context)!.cruiseNavigatorSubscribe),
          BottomNavigationBarItem(icon: Icon(Icons.rss_feed), label: AppLocalizations.of(context)!.cruiseNavigatorChannel),
          BottomNavigationBarItem(icon: Icon(Icons.school), label: AppLocalizations.of(context)!.cruiseNavigatorMine),
        ],
        currentIndex: state.selectIndex,
        fixedColor: Theme.of(context).primaryColor,
        onTap: _onItemTapped,
        unselectedItemColor: Color(0xff666666),
        type: BottomNavigationBarType.fixed),
  );

the InkWell works with double tap but did not trigger the single tap event.

Remove the parent GestureDetector of your BottomNavigationBar and replace inkwell with GestureDetector and then set the behavior of your GestureDetector to HitTestBehavior.translucent.
