Add DateTime option in custom markedDateWidget about flutter_calendar_carousel HOT 9 CLOSED

I've modified the widget to have this for my personal use with also square or line markers. For that I've modified the API to accept a Map<DateTime, List<DateMarkWidget>>.
Therefore, when you provide the markers to the Calendar widget, you need to generate before all the widget for the month.
It's not a callback function in order to prevent it to stop the month widget to display the dates. If you have to perform some actions on each date to return the correct widget, the Calendar Widget will have to wait until you return the widget to process the following date.
So I've kept the current way the widgets are added to the calendar with some tweaks. When the month (or week) is changed, it emits an event which can be listened from the parent widget onMonthChanged(DateTime). This tells the parent widget that the month have changed and which date is actually displayed (first day of the month or first day of the week displayed). You can listen to it and generates the marked dates widget in a List<DateMarkWidget> for each day and add them into a Map<DateTime, List<DateMarkWidget>> and finally change the state of the parent widget.
There is also a helper from the DateMarkWidget which can create the widget wanted: DateMarkWidget.square, DateMarkWidget.dot, DateMarkWidget.line or DateMarkWidget.custom (for custom widget).

So the final behavior is: the calendar is first displayed without marking, the calendar tells the current month displayed, the parent widget generates the marked widgets, the parent widget update its state, the calendar widget receive the new marked dates and update itself.
Tip: The devs can also add a loading animation when generating the marked widgets to tell the user that the month is not fully displayed yet.

If it's what was intended, I can prepare a PR with what I've modified/added.

@dooboolab I will be PRing this after resolving the previous PR (since it's kind of based on it).

I don't quite get what you want here.

You can set markedDateWidget and also markedDatesMap that gets the Datetime and the number of marked uis.

I want to have different marked date widgets on the same date. The current method makes the marked dates same color or same widget. So some function which says on 28th return a list of markedDate widgets.
