With the same Day. JS API time processing library, convenient to do DateTime operation.
DayDart #
Time-handling library with day.js API.
Getting Started #
This project is a starting point for a Dart package, a library module containing code that can be shared easily across multiple Flutter or Dart projects.
For help getting started with Flutter, view our online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.
Install #
Run this command under your project
dart pub add daydart
# or
flutter pub add daydart
API #
The DayDart object is immutable, and all calls will return a new DayDart object.
Parsing #
Passing in the supported format in DayDart.
Now Time
Calling DayDart() with no arguments returns a new DayDart object containing the current date and time
DayDart now = DayDart()
String
Parses the given string in ISO 8601 format and returns an instance of the DayDart object.
DayDart('2018-04-04')
DateTime
A DateTime object passed in.
DayDart(DateTime.now());
Timestamp
Create DayDart with an integer value of milliseconds
DayDart(1623484401193);
Clone
All DayDart objects are immutable. Dayart#clone can still create a clone of the current object if needed.
DayDart a = DayDart()
DayDart b = a.clone()
Calling DayDart() on the DayDart object also clones it.
DayDart a = DayDart()
DayDart b = DayDart(a)
Valid
Returns a Boolean indicating whether the DayDart object contains an expiration date.
DayDart().isValid()
Get #
Year
Gets or sets the year.
DayDart().year();
DayDart().year(2000);
Month
Gets or sets the month.
Accept numbers from 1 to 12. If it exceeds that range, it will continue until the end of the year.
DayDart().month();
DayDart().month(1);
Quarter
Gets or sets the quarter.
DayDart('2010-04-01').quarter() // 2
DayDart('2010-04-01').quarter(2)
Day
Gets or sets the date of the month.
Accept numbers from 1 to 31. If this range is exceeded, it will last until the day.
DayDart().day()
DayDart().day(1)
Days
Gets the total number of days of the month
DayDart().days()
DayOfYear
Total number of days from date to year
DayDart().dayOfYear()
Weeks

Week
For week
DayDart().week()
Hour
Gets or sets the hour.
Accept the numbers from 0 to 59. If this range is exceeded, it will last until the day.
DayDart().hour()
DayDart().hour(12)
Minute
Gets or sets the minutes.
Accept the numbers from 0 to 59. If this range is exceeded, it will last until hours
DayDart().minute()
DayDart().minute(12)
Second
Gets or sets the seconds.
Accept the numbers from 0 to 59. If this range is exceeded, it will last up to minutes.
DayDart().second()
DayDart().second(12)
Millisecond
Gets or sets milliseconds.
Accepts numbers from 0 to 999. If this range is exceeded, it will last up to seconds.
DayDart().millisecond()
DayDart().millisecond(12)
Operation #
Once you have a DayDart object, you might want to manipulate it in some way.
DayDart supports method links like this:
DayDart('2019-01-25')..add(1, DayUnits.D)..subtract(1, DayUnits.y)..year(2009)..toString()
List of all available units
| uni | desc |
|---|---|
| D | day (1-31) |
| M | month(1-12) |
| y | year |
| h | hour |
| m | minutes |
| s | seconds |
| ms | millisecond |
Add
Returns a cloned DayDart object, adding the specified time.
DayDart().add(7, DayUnits.D)
Subtract
Returns the cloned 'DayDart' object, subtracting the specified time.
DayDart().subtract(7, DayUnits.D)
Query #
List of all available units
| unit | desc |
|---|---|
| D | day |
| M | month |
| y | year |
| h | hour |
| m | minutes |
| s | seconds |
| ms | millisecond |
isBefore
This indicates whether the DayDart object is before another supplied date-time.
DayDart().isBefore(DayDart('2011-01-01')) // default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a second argument.
DayDart().isBefore('2011-01-01', DayUnits.y)
isSame
This indicates whether the DayDart object is the same as the date-time provided by another.
DayDart().isSame(DayDart('2011-01-01')) // default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a second argument.
DayDart().isSame('2011-01-01', DayUnits.y)
isAfter
This indicates whether the DayDart object is after another supplied date-time.
DayDart().isAfter(DayDart('2011-01-01')) // default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a second argument.。
DayDart().isAfter('2011-01-01', DayUnits.y)
isSameOrBefore
This indicates whether the DayDart object is the same or before another provided date-time.
DayDart().isSameOrBefore(DayDart('2011-01-01')) // default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a second argument.
DayDart().isSameOrBefore('2011-01-01', DayUnits.y)
isSameOrAfter
This indicates whether the DayDart object is the same or after another supplied date-time.
DayDart().isSameOrAfter(DayDart('2011-01-01')) // default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a second argument.
DayDart().isSameOrAfter('2011-01-01', DayUnits.y)
isBetween
This indicates whether the DayDart object is between the other two supplied date-times.
DayDart('2010-10-20').isBetween('2010-10-19', DayDart('2010-10-25'))// default milliseconds
If you want to limit granularity to units rather than milliseconds, pass it as a third parameter.
DayDart().isBetween('2010-10-19', '2010-10-25', DayUnits.y)
isDayDart
This indicates whether the variable is a DayDart object.
DayDart.isDayDart(DayDart()) // true
DayDart.isDayDart(DateTime.now()) // false
You can also use the is operator:
DayDart() is DayDart // true
isLeapYear
This indicates whether the year of the DayDart object is a leap year.
DayDart('2000-01-01').isLeapYear() // true
Display #
Format
Gets the formatted date based on the passed token string.
To escape characters, enclose them in square brackets (for example, 'MM').
DayDart().format()
DayDart('2019-01-25').format('dd/MM/yyyy') // '25/01/2019'

To DateTime
To get a copy of the local date object parsed from the 'dayDart' object, use dayDart #toDate.
DayDart('2019-01-25').toDate()
To List
DayDart('2019-01-25').toList() // [ 2019, 0, 25, 0, 0, 0, 0 ]
To Map

DayDart('2019-01-25').toMap()
/*
{

minutes: 0,
seconds: 0,
milliseconds: 0
}
*/
To IOS 8601 String
Formatted as an ISO 8601 string.
