format_date_x

A flexible date formatting and conversion package with optional BLoC support.

Features

• Built-in date formats (ISO, US, EU, display, long, short, time, datetime, epoch, relative)
• Custom format registration
• Two-word format conversion (iso→display, us→eu)
• String and DateTime extensions
• Optional BLoC integration (import separately to avoid dependency conflicts)

Installation

Add to your pubspec.yaml:

dependencies:
  format_date_x: ^1.0.0

For date conversion only, that is all you need. The core package depends only on intl and works in Dart or Flutter apps without pulling in BLoC or Flutter SDK constraints.

Usage

Date conversion (recommended import)

import 'package:format_date_x/date_x.dart';

// Core API
DateX.convert('2024-01-15', 'iso→display'); // 15 Jan 2024
DateX.convert('01/15/2024', 'us→eu');       // 15/01/2024

// Extensions
'2024-01-15'.dateX('iso→us');               // 01/15/2024
DateTime.now().formatX('long');             // January 15, 2024

// Custom formats
DateX.register('myapi', 'dd-MM-yyyy');
DateX.convert('15-01-2024', 'myapi→display');

// Validation
DateX.isValid('2024-01-15', 'iso');         // true

BLoC (optional, separate import)

Only import BLoC when you need reactive date operations. Your app already uses flutter_bloc for UI — format_date_x does not force a conflicting version.

import 'package:format_date_x/date_x_bloc.dart';
import 'package:flutter_bloc/flutter_bloc.dart';

BlocProvider(
  create: (_) => DateXBloc(),
  child: BlocBuilder<DateXBloc, DateXState>(
    builder: (context, state) { /* ... */ },
  ),
);

Avoiding package conflicts

Importing only date_x.dart keeps your dependency tree minimal (intl only) and avoids version clashes with flutter_bloc, equatable, or other packages in your app.
