We sometimes see this ANR popup in Google Play Console only on Android 12 devices,

This binder call may be taking too long, causing the main thread to wait and triggering the ANR. [Learn more](https://developer.android.com/topic/performance/anrs/find-unresponsive-thread#slow-binder)

I am using it under popscope to show the user a toast before exiting the app.

 if (isFirstRouteInCurrentTab) {
          if (navController.currentPage.value != "DashboardKey") {
            navController.selectTab(tabItem: "DashboardKey", index: 0);
          } else {
            debugPrint('Exit');
            DateTime now = DateTime.now();
            if (currentBackPressTime == null || now.difference(currentBackPressTime!) > const Duration(seconds: 2)) {
              currentBackPressTime = now;
              Fluttertoast.showToast(
                msg: 'Click again to exit',
                toastLength: Toast.LENGTH_SHORT,
                gravity: ToastGravity.CENTER,
                timeInSecForIosWeb: 1,
                backgroundColor: Colors.black54,
                textColor: Colors.white,
                fontSize: 16.sp,
              );
            } else {
              SystemNavigator.pop();
              exit(0);
            }
          }
        }
