Updated issue with Flutter

Renamed inheritFromWidgetOfExactType to dependOnInheritedWidgetOfExactType

I don't know if you've had this issue, but it helped me to continue to use this package, so thought I'd share it. Thanks for an awesome package BTW!

Anybody who needs it before then can add to dependency_overrides in their pubspec.yaml

dependency_overrides:
  calendar_views: #https://github.com/zenled/calendar_views/pull/28 The method 'inheritFromWidgetOfExactType' isn't defined for the class 'BuildContext'
    git: https://github.com/m8iog/calendar_views.git
