Quick Start

import 'package:prism_flutter/prism_flutter.dart';

// Convert RayRgb8 to Flutter Color
final ray = RayRgb8.fromHex('#FF0000');
final color = ray.toColor();

// Convert Flutter Color to RayRgb8
final backToRay = Colors.red.toRayRgb8();

Usage

RayRgb8 to Flutter Color

final red = RayRgb8.fromHex('#FF0000');
final color = red.toColor();
final transparent = red.toColorWithOpacity(0.5);

Flutter Color to RayRgb8

final color = Colors.blue;
final ray = color.toRayRgb8();

Enhanced Color Operations

// Chain operations using both Flutter and Prism methods
final result = Colors.red
    .toRayRgb8()
    .withOpacity(0.8)
    .lerp(Colors.blue.toRayRgb8(), 0.3)
    .toColor();

// Generate accessibility schemes
final scheme = Spectrum.fromRay(Colors.blue.toRayRgb8());
final textColor = scheme.source.onRay.toColor();

Color Palettes

Access pre-built color palettes with Flutter integration:

import 'package:prism_flutter/prism_flutter.dart';
import 'package:prism/palettes/rgb/material.dart';

final materialBlue = MaterialRgb.blue.shade500.toColor();
final primaryColor = MaterialRgb.indigo.source.toColor();
