type 'Future<dynamic>' is not a subtype of type 'Map<DateTime, List<Event>>'

Question

Hi I'm trying to convert a Future list into a LinkedHashMap and I'm having But I'm returning a Future Dynamic

This is my class

class Event {
  final String calendarDatesStart;
  final String eventTitle;

  const Event(this.calendarDatesStart, this.eventTitle, );

  @override
  String toString() => eventTitle;
}

// Gets the Future
var datasource = const FutureCalendarEvents();

getCalendarDataSource() async {
  return await datasource.getCalendarFuture();
}

My function to return the Map

// Add dates to eventsMap ??
myDates () async {

  var eventsMap = <DateTime, List<Event>>{};
  List myDatesEvents = await getCalendarDataSource();

  for(var item in myDatesEvents){
    print(item);
    eventsMap.update(DateTime(item.calendarDatesStart), 
item.calendarEventName);
  }
    return eventsMap;
}

And here is where it takes my events

// Takes my events
final kEvents = LinkedHashMap<DateTime, List<Event>>(
  equals: isSameDay,
  hashCode: getHashCode,
)..addAll(eventsMap);

And this is what I end up with

Thanks for any help I've been at this a long time trying to work it out.
