```

2.import flutter_custom_calendar lib

```

3.create CalendarViewWidget object，profile CalendarController

        minYear: 2018,
        minYearMonth: 1,
        maxYear: 2020,
        maxYearMonth: 12,
        showMode: CalendarConstants.MODE_SHOW_MONTH_AND_WEEK);

## 2.0 version
Major changes：
* The UI configuration related parameters are moved to the calendar view construction method (the old version is configured in the controller)
* Calendar supports padding and margin attributes, and item size calculation and modification.
* Realize the overall adaptive height of calendar
* The controller provides the method of changing extradatamap, which can dynamically modify the customized data extradatamap at any time.
* It supports the display of monthly view and weekly view, with weekly view as the priority, and mode "show" week "and" month "
* Supports verticalspacing and itemsize properties


## matters needing attention

* If you use the version before 2.0, you need to move the UI configuration related parameters to the calendar view construction method (the old version is configured in the controller).
* I haven't found any other problems for the time being. If you have any, please let me know.
* If you use this library to make a calendar, you can share the display results with me, and I will paste them on the document for display.
