ColorPalette.polyad constructor

ColorPalette.polyad(Color seed, { int numberOfColors = 5, num hueVariability = 0, num saturationVariability = 0, num brightnessVariability = 0, bool perceivedBrightness = true, bool clockwise = true, bool growable = true, bool unique = false, })

Generates a ColorPalette by selecting colors with hues evenly spaced around the color wheel from color.

numberOfColors defaults to 5, must be > 0 and must not be null.

hueVariability, saturationVariability, and brightnessVariability, if > 0, add a degree of randomness to the selected color's hue, saturation, and brightness (HSB's value) values, respectively.

hueVariability defaults to 0, must be >= 0 && <= 360, and must not be null.

saturationVariability and brightnessVariability both default to 0, must be >= 0 && <= 100, and must not be null.

  bool clockwise = true,
  bool growable = true,
  bool unique = false,
}) {
  assert(numberOfColors > 0);
  assert(hueVariability >= 0 && hueVariability <= 360);
  assert(saturationVariability >= 0 && saturationVariability <= 100);
  assert(brightnessVariability >= 0 && brightnessVariability <= 100);
