I solved this problem :

from flutter_calendar_carousel.

this works for me... on the file C:\src\flutter.pub-cache\hosted\pub.dartlang.org\flutter_calendar_carousel-2.2.0\lib\flutter_calendar_carousel.dart

on the line 326
make this change

-- headerTitle: headerText ?? widget.weekFormat ? '${_localeDate.format(_weeks[_pageNum].first)}' : '${_localeDate.format(_dates[_pageNum])}',

++ headerTitle: headerText ?? (widget.weekFormat ? '${_localeDate.format(_weeks[_pageNum].first)}' : '${_localeDate.format(_dates[_pageNum])}'),

from flutter_calendar_carousel.
