  • `_events[someDate].removeMethod(...)` - where `removeMetod` is one of: `remove, removeAt, removeLast, removeRange, removeWhere` – pskink Nov 18 '20 at 07:00

Use removeWhere()

Remove based on Date

_events.removeWhere((key, value) => key == myDateObject);

Remove based on Event List

_events.removeWhere((key, value) => value == eventList);

In the second case, do remeber it will apply default list comparision which means both lists should have same objects in the same order. If you want you can provide your custom list comparisions. Check this
