API 30 error.

[beeay]

Hi! I am seeing that it is working fine in iOS, and android api 28 and 29, but it returns an error with 30.
It fails when execute:

    final Event event = Event(
      title: 'Event title',
      description: 'Event description',
      location: 'Event location',
      startDate: DateTime.now(),
      endDate: DateTime.now(),
      iosParams: const IOSParams(
        reminder: Duration( hours:1), // on iOS, you can set alarm notification after your event.
      ),
      androidParams: const AndroidParams(
        emailInvites: [], // on Android, you can add invite emails to your event.
      ),
    );

    Add2Calendar.addEvent2Cal(event);

Error:
