../../../../../flutter/.pub-cache/hosted/pub.dartlang.org/flutter_calendar_carousel-2.3.0/lib/flutter_calendar_carousel.dart:950:33: Error: Method 'addPostFrameCallback' cannot be called on 'WidgetsBinding?' because it is potentially null.

I think #313 patch will work which is published in version 3.2.1.

Please try this and come back.

reproduced the issue with flutter 2.5.3

313 will fix this but will break flutter 3.0
