lhengl / date_time

Adding additional features for working with week, month and year

date_time

Package to work with Date & Time in separation and with its ranges.

This project will be useful for projects that are related to booking.

Features

• Only Date comparison
• Only Time comparison
• Overflowed Time with keeping days
• Find crossing of dates
• Find crossing of times in the day

Getting started

1. Add dependency

dependencies:
  date_time: <newest>

2. Import the dependency

import 'package:date_time/date_time.dart';

Usage

Please, check (examples) folder for more advanced examples.

Date

// Get [Date] & [Time] from [DateTime]
print(DateTime(2022, 1, 6).date); // prints 1/6/2022
print(DateTime(7, 38, 24).time); // 07:38:24

given('DateTime', () {
  final dateTime = DateTime(2020, 11, 30, 14, 33, 17);

  then('[Date] should be equal to', () {
    dateTime.date.should.be(Date(year: 2020, month: 11, day: 30));
  });

  then('[Time] should be equal to', () {
    dateTime.time.should.be(Time(hour: 14, minute: 33, second: 17));
  });
});

CopyWith

final date = Date(year: 2021, month: 3, day: 7);
print(date.copyWith(year: 2022)); // prints 07/03/2022

DateRange

final range = DateRange(
  const Date(year: 2021, month: 1, day: 1),
  const Date(year: 2021, month: 12, day: 31),
);

test('should be valid', () {
  range.isValid.should.beTrue();
});

Time

final time2 = time.addMinutes(30);
final isTime2After = time2 > time;
final isTime2After2 = time2.isAfter(time);
print('Is time2 after: $isTime2After');

CopyWith

  final time = Time(hour: 6, minute: 30, second: 7);
  print(time);                      // prints 06:30:07
  print(time.copyWith(second: 0));  // prints 06:30:00

Overflowed Time

to keep days

final time = Time(hour: 20).addHours(5);

print(time is OverflowedTime); // prints `true`
print(time.asOverflowed.days); // prints `1`

TimeRange

// TimeRange crossing
final timeRange = TimeRange(Time.now, Time.now.addHours(6));
final timeRange2 = TimeRange(Time.now.addHours(3), Time.now.addHours(9));

final isCrossing = timeRange.isCross(timeRange2);
print('Time ranges are crossing: $isCrossing');

Override time with clock package

withClock(
    Clock(() => DateTime.now().subtract(Duration(days: 10, minutes: 214))),
    () {
        print(clock.now());                    // 2022-06-21 16:28:46.366887
        print(DateTime.now());                 // 2022-07-01 20:02:46.367579    
        print('${Date.now()} ${Time.now()}');  // 6/21/2022 16:28:46                  
    },
);
