Hybrid Hex Color Converter

A useful tool for working with hexadecimal colors in Flutter. This package provides an extension called HybridHexColor that can be used on Color objects in Flutter.

What's New in 0.0.3

Fixed deprecated Color properties for better compatibility with latest Flutter versions
Updated to use non-deprecated getters (a, r, g, b instead of alpha, red, green, blue)
Fixed color component conversion from normalized values (0.0-1.0) to 0-255 range
Updated tests to use toARGB32() instead of deprecated .value property
Improved documentation and examples
Previous HexColor extension is now deprecated (use HybridHexColor instead)

Features

fromHex(String hexString): Converts a hexadecimal string into a Color object. The string can be in formats like "aabbcc" or "ffaabbcc" and may include an optional "#" sign at the beginning.
toHex({bool leadingHashSign = true}): Returns the hexadecimal representation of a color in the AARRGGBB format. You can specify whether to include the "#" sign at the beginning of the hexadecimal code.

Installation

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

dependencies:
  hybrid_hex_color_converter: ^0.0.4

Usage

Import the package into your Flutter file and use the HybridHexColor extension on Color objects to convert colors to and from hexadecimal formats easily and efficiently.

Examples

Convert a hexadecimal string to a Color object:

import 'package:flutter/material.dart';
import 'package:hybrid_hex_color_converter/hybrid_hex_color_converter.dart';

void main() {
  // Convert hex strings to Color objects
  Color red = HybridHexColor.fromHex("#FF0000");
  Color green = HybridHexColor.fromHex("#4CAF50");
  Color blue = HybridHexColor.fromHex("#2196F3");

  // Works with or without the # symbol
  Color white = HybridHexColor.fromHex("ffffff");
  Color black = HybridHexColor.fromHex("#000000");

  print(red);   // Color(0xffff0000)
  print(white); // Color(0xffffffff)
}

Convert a Color object to a hexadecimal string:

import 'package:flutter/material.dart';
import 'package:hybrid_hex_color_converter/hybrid_hex_color_converter.dart';

void main() {
  // With leading hash sign (default)
  String greenHex = Colors.green.toHex();
  print(greenHex); // #FF4CAF50

  // Without leading hash sign
  String blueHex = Colors.blue.toHex(leadingHashSign: false);
  print(blueHex); // FF2196F3

  // Works with any Color object
  Color customColor = Color.fromARGB(255, 150, 100, 200);
  String customHex = customColor.toHex();
  print(customHex); // #FF9664C8
}

Migration from 0.0.2

If you're upgrading from version 0.0.2, simply replace HexColor with HybridHexColor in your code:

// Old (deprecated but still works)
Color color = HexColor.fromHex("#FF0000");

// New (recommended)
Color color = HybridHexColor.fromHex("#FF0000");
