Function "remove" in class "EventList<T>" return not correct

[tdinhv]

Version of flutter_calendar_carousel

1.4.11

Expected behavior

Result is false

Actual behavior

Result is true

flutter doctor result (run flutter doctor in terminal)

Steps to reproduce the behavior

bool remove(DateTime date, T event) {
    return events != null && events.containsKey(date)
        ? events[date].remove(event)
        : true;
  }

In this func, i think if events.containsKey(date) == false it should return false.
EX:

   bool remove(DateTime date, T event) {
    return events != null && events.containsKey(date)
        ? events[date].remove(event)
        : false;
  }
