Date manipulation library for easy calculating.

Usage

Installation

Add date_calc as a dependency in pubspec.yaml file.

dependencies:
  date_calc: ^0.1.0

Run pub install.

Using

import 'package:date_calc/date_calc.dart';

final date = DateCalc(2019, 1, 5);
print(date.addMonth(1));
// => 2019-02-05 00:00:00.000
print(date.addYear(1).isLeapYear());
// => true
print(date.addYear(1).addMonth(1).daysInMonth());
// => 29
print(date.dup(minute: 11));
// => 2019-01-05 00:11:00.000
print(date.differenceValue(date: DateTime(2019, 3, 3), type: DateType.month));
// => 1
print(DateCalc.now().isToday());
// => true

Because DateCalc is a subclass of DateTime, you can use all DateTime methods.
When you need exactly DateTime object, use toDate() method.

final date = DateCalc(2019, 1, 5);
date.subtractYear(1).toDate();

date_calc's Issues

[Feature] Implement method to determine not `x`day yet

Warning when their Timezone is different comparing self with other

• Including isUtc or not
• return value with own Timezone and puts warning

Extend toFormattedString

toFormattedString should receive string separated with /.

Override instance methods

Override some instance methods and return DateCalc instance.

Optional parameter for `isUtc`

Need more flexible constructor

More flexible constructor which returns like 'Yesterday's 6:00 PM', 'Last year 1/1 0:00'.

Impliment replacement of add, subtract

Implement methods receive Map and return DateCalc instance.
