With shiny extensions, if you have ever written something like this, then look no further:

final DateTime fourHoursFromNow = DateTime.now() + Duration(hours: 4);

video_game Usage

final Duration tenMinutes = 10.minutes;
final Duration oneHourThirtyMinutes = 1.5.hours;
final DateTime afterTenMinutes = DateTime.now() + 10.minutes;
final Duration tenMinutesAndSome = 10.minutes + 15.seconds;
final int tenMinutesInSeconds = 10.minutes.inSeconds;
final DateTime tenMinutesFromNow = 10.minutes.fromNow;

You can perform all basic arithmetic operations on Duration as you always have been:

final Duration interval = 10.minutes + 15.seconds - 3.minutes + 2.hours;
final Duration doubled = interval * 2;

You can also use these operations on DateTime:

final DateTime oneHourAfter = DateTime() + 1.hours;

Duration is easily convertible as it always has been:

final int twoMinutesInSeconds = 2.minutes.inSeconds;

You can also convert Duration to DateTime, if needed:

final DateTime timeInFuture = 5.minutes.fromNow;
final DateTime timeInPast = 5.minutes.ago;

Iterate through a DateTime range:

final DateTime start = DateTime(2019, 12, 2);
final DateTime end = start + 1.weeks;
final DateTime tuesday = start.to(end).firstWhere((date) => date.weekday == DateTime.tuesday);

You can also delay code execution:

void doSomething() async {
  await 5.seconds.delay;
  // Do the other things
}

You can also use the popular copyWith:

final initial = DateTime(2019, 2, 4, 24, 50, 45, 1, 1);
final expected = initial.copyWith(
  year: 2021,
  month: 10,
  day: 28,
  hour: 12,
  minute: 45,
  second: 10,
  millisecond: 0,
  microsecond: 12,
);
