Returns a new DateTime instance with duration
added to this.
var today = new DateTime.now(); var fiftyDaysFromNow = today.add(new Duration(days: 50));
Notice that the duration being added is actually 50 * 24 * 60 * 60 seconds. If the resulting DateTime
has a different daylight saving offset than this
, then the result won't have the same time-of-day as this
, and may not even hit the calendar date 50 days later.
Be careful when working with dates in local time.
external DateTime add(Duration duration);
