Usage #

Predefined Color Scales #

FlyColor provides predefined color scales for all colors:

import 'package:flycolor/colors.dart';

// Direct access (defaults to light mode)
FlyColor.blue9;        // Step 9 (seed/base color)
FlyColor.blue1;        // Lightest step
FlyColor.blue12;       // Darkest step
FlyColor.blueContrast; // Contrast color for text
FlyColor.blueSurface;  // Surface color

// Dark mode variants
FlyColor.blue1Dark;
FlyColor.blue9Dark;

// Explicit light/dark mode
FlyColorLight.blue1;
FlyColorDark.blue1;

// Context-aware (automatically switches based on theme)
FlyColor.of(context).blue1;
FlyColor.of(context).gray9;

Generating Custom Color Scales (Advanced) #

For custom color schemes, you can generate scales from any accent, gray, and background colors:

import 'package:flycolor/generator.dart';

final colors = FlyColorGenerator.generate(
  appearance: 'light',
  accent: '#3D63DD',
  gray: '#8B8D98',
  background: '#FFFFFF',
);

// Access the generated scales
colors.accentScale;      // 12-step accent scale
colors.grayScale;        // 12-step gray scale
colors.accentScaleAlpha; // Alpha variants
colors.accentContrast;   // Contrast color for text
colors.accentSurface;    // Surface color
