Dated

dated is a Dart package that provides useful extensions for working with DateTime objects. It includes extensions for comparing dates, checking if dates are the same day, month, or year, and calculating the time ago from a given date.

Installation

Add the dated package to your pubspec.yaml file:

dart pub add dated

Usage

Import the dated package in your Dart file:

import 'package:dated/dated.dart';

DatedBaseBoolExtension

The DatedBaseBoolExtension provides methods to compare DateTime objects.

final today = DateTime.now();
final yesterday = today.subtract(const Duration(days: 1));
final nextMonth = today.add(const Duration(days: 30));

print(today.isSameDay(yesterday)); // false
print(today.isSameMonth(nextMonth)); // false
print(today.isSameYear(nextMonth)); // true
print(yesterday.isBeforeDay(today)); // true
print(today.isBeforeMonth(nextMonth)); // true
print(nextMonth.isAfterYear(today)); // false

DatedBaseTimeAgoExtension

The DatedBaseTimeAgoExtension provides a method to calculate the time ago from a given DateTime object.

final twoHoursAgo = DateTime.now().subtract(const Duration(hours: 2));
final threeDaysAgo = DateTime.now().subtract(const Duration(days: 3));
final sixMonthsAgo = DateTime.now().subtract(const Duration(days: 180));

print(twoHoursAgo.timeAgo()); // 2 hours ago
print(threeDaysAgo.timeAgo()); // 3 days ago
print(sixMonthsAgo.timeAgo()); // 6 months ago

print(threeDaysAgo.timeAgo(prefix: 'Posted')); // Posted 3 days ago
print(sixMonthsAgo.timeAgo(suffix: 'earlier')); // 6 months earlier
print(twoHoursAgo.timeAgo(prefix: 'Created', suffix: 'ago')); // Created 2 hours ago
