Hi, the widget looks great! But I couldn't figure out how can i set the date range to include a year and a half for example. I was only able to show the current year. and when trying to scroll to next / previous year i got this error:

Was able to fix it by setting onMonthChanged: (_){}, property, but maybe it will be a good idea to add a date range?

I'll try to reproduce your problem. Let me see.

Should be fixed with https://github.com/rwbr/flutter_neat_and_clean_calendar/issues/73#issuecomment-1984355529
