GestureDetector( onLongPressUp: () { showCupertinoModalBottomSheet( isDismissible: true, backgroundColor: lightBlackNavBar, useRootNavigator: true, context: context, duration: Duration(milliseconds: 200), builder: (context) => Container( height: 300, child: Center(child: Text('I tuoi account')), ), ); },

I'm trying to open the bottom modal sheet but when I tap outside to dismiss the bottom sheet it throws the error:
