Custom url for calendar events

[aloisdeniel]

It would be great to have an url property at the event level to be able to identify (update for example) an event.

The property seems to be available on both platform :

• iOS
• Android

@aloisdeniel this was added in #136
and has now been published

Thanks a lot @nickrandolph !

If I may ... a great addition would be to be able to retrieve an event from its url too! :)

Because with current APIs we need to load all events to check if it already exists.

final events = await systemCalendar.retrieveEvents(calendarId, RetrieveEventsParams(
     eventUrls : ["custom://events/563"],
));

@aloisdeniel we'll have to investigate how easily we can search for events on each platform based on the url attribute.
