time_since 1.0.0

convert DateTime and Unix timestamps into human-readable 'time-ago' strings

time_since

A Flutter package that converts timestamps into human-readable time-ago strings (e.g., "2 hours ago", "3 months ago").

Features

• Convert timestamps or DateTime objects into human-readable time strings
• Customizable output format
• Support for multiple time units (years, months, days, hours, minutes, seconds)
• "Just now" threshold for very recent times
• Configurable precision for time descriptions
• Automatic pluralization of time units

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  time_since: ^1.0.0

Then run:

flutter pub get

Usage

Basic Usage

import 'package:time_since/time_since.dart';

// Using with DateTime
final dateTime = DateTime(2024, 1, 1);
print(timeSince(dateTime)); // "3 months ago"

// Using with Unix timestamp (seconds)
final timestamp = 1704067200; // January 1, 2024
print(timeSince(timestamp)); // "3 months ago"

Customizing Output

You can customize the output format using TimeFormatOptions:

final options = TimeFormatOptions(
  addAgo: false,         // Don't append "ago" to the result
  maxPrecision: 2,       // Show up to 2 units (e.g., "1 year, 2 months")
  justNowThreshold: 60,  // Show "just now" for times within 60 seconds
);

final time = DateTime.now().subtract(Duration(hours: 25));
print(timeSince(time, options)); // "1 day, 1 hour"

API Reference

timeSince

String timeSince(dynamic time, [TimeFormatOptions? options])

Formats a time into a human-readable time-ago string.

Parameters:

• time: Either a Unix timestamp (int) or a DateTime object
• options: Optional TimeFormatOptions to customize the output

Returns a formatted string like "2 hours ago" or "3 months ago".

TimeFormatOptions

class TimeFormatOptions {
  final bool addAgo;            // Whether to append "ago" to the result
  final int maxPrecision;       // Maximum number of units to show
  final int justNowThreshold;   // Seconds threshold for "just now"
  
  const TimeFormatOptions({
    this.addAgo = true,
    this.maxPrecision = 1,
    this.justNowThreshold = 30,
  });
}

Time Units

The package supports the following time units:

• Years
• Months
• Days
• Hours
• Minutes
• Seconds

Time units are automatically pluralized based on the value (e.g., "1 month" vs "2 months").
