app_color_parser

app_color_parser is a simple and lightweight Dart package for Flutter that provides utilities to convert between Color and hex string or integer formats, and also includes tools for easy JSON serialization and deserialization of color values.

Features

• Convert Color objects to and from hex strings (e.g., #RRGGBB, 0xAARRGGBB).
• Convert Color objects to and from int values (ARGB).
• JSON serialization helpers for both hex and int formats.

Getting Started

Add the dependency to your pubspec.yaml:

dependencies:
  app_color_parser: ^0.0.4

Usage

Convert Color to Hex String

final color = Colors.blue;
final hex = color.toHex(); // e.g., '0xFF2196F3'

Convert Hex String to Color

final color = HexColorExtension.fromHex('0xFF2196F3');

Use JSON Helpers

ARGB Int Helper

final helper = ColorJsonHelper();
final jsonValue = helper.toJson(Colors.red); // e.g., 0xFFFF0000
final color = helper.fromJson(jsonValue);

Hex String Helper

final helper = HexColorJsonHelper();
final jsonValue = helper.toJson(Colors.green); // e.g., '0xFF4CAF50'
final color = helper.fromJson(jsonValue);
