Simple and clean flutter calendar with ability to slide up/down to show weekly/monthly calendar. Forked from [flutter_clean_calender](https://pub.dev/packages/flutter_clean_calendar)
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:
