calendar_time

Implementation of MomentJS's calendarTime function and some other helpful utilities.

I expect this project will get replaced with another more ambitious project in the future, but this has come in very handy. Extensions and pull requests welcome.

Usage

toHuman

Converting a DateTime to a human readable string

import 'package:calendar_time/calendar_time.dart';

main(){
  CalendarTime(DateTime.now()).toHuman; //Today at {current time}
}

Example output:

• Today at {current time}
• Tomorrow at {time}
• Yesterday at {time}
• {day} at {time}
• Last {day} at {time}
• date time (outside of the last or upcoming few weeks)

Honestly just check the code, but it is in line with Moment's logic.

You can also call .toHumanMultiLine that splits the output around at to have date and time on different lines.

formatTime

Formats time to current timezone in hours and minutes

import 'package:calendar_time/calendar_time.dart';

main(){
  CalendarTime(DateTime.now()).timeFormat; //Today at {current time}
}

You can change the format this way:

import 'package:calendar_time/calendar_time.dart';

main(){
  final calendarTime = CalendarTime(DateTime.now());
  calendarTime.timeFormat = DateFormat.jms(); //for hours minutes seconds
  print(calendarTime.timeFormat); //Today at {current time}
}

See https://pub.dev/documentation/intl/latest/intl/DateFormat-class.html for options.
