With shiny extensions, if you have ever written something like this, then look no further:
final DateTime fourHoursFromNow = DateTime.now() + Duration(hours: 4);
dependencies:
time: "^2.1.5"
import 'package:time/time.dart';
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);
Granular comparison between DateTime
fields:
final DateTime specificDate = DateTime(2021, 01, 01);
final DateTime otherDate = DateTime(2021, 02, 01);
print(specificDate.isAtSameYearAs(otherDate)); // true
print(specificDate.isAtSameMonthAs(otherDate)); // false
print(specificDate.isAtSameDayAs(otherDate)); // false
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,
);
