I need to change the font size of CupertinoDatePicker so it looks more like native one. The font is small compared to ios datepicker. For the height wrapping in a Container with height of MediaQuery.of(context).copyWith().size.height / 3 makes the height to be similar to native one.

                fontSize: 16,
            ),
        ),
     ),
     child: CupertinoDatePicker(
          ...
