CustomScrollViewerLayout: A constant constructor can't call a non-constant super constructor

Hi!

Thank you for your for your awesome SfCalendar product! We recently upgraded to 21.2.5 and face the following error:

../../../hostedtoolcache/flutter/stable-3.7.11-x64/.pub-cache/hosted/pub.dev/syncfusion_flutter_core-21.2.5/lib/src/calendar/custom_looping_widget.dart:50:9: Error: A constant constructor can't call a non-constant super constructor.
      : super(children: children);
        ^

When I remove

const

in front of the 

CustomScrollViewerLayout constructor my code compiles again.
