Usage

Getting random color:

random color function can be called with parameters colorHue, colorSaturation and colorBrightness allowing for customization of colors the generator will pass.

import 'package:random_color/random_color.dart';

RandomColor _randomColor = RandomColor();

Color _color = _randomColor.randomColor();

Getting color name:

You can get color name from hex string (without # and alpha hex values) or from Color object

  Color _color = Color('FF0000'.toStringRadix(16));
  MyColor _myColor = getColorNameFromColor(_color);

  // Prints: 'Red'
  print(_myColor.getName);

Get just red colors:

Random color can generate just specific color type, as long hue, saturation and brightness are not too limiting this will still give rich result

import 'package:random_color/random_color.dart';

RandomColor _randomColor = RandomColor();

Color _color = _randomColor.randomColor(colorHue: ColorHue.red);

Get just red and blue colors:

You can combine multiple hue ranges to choose from

import 'package:random_color/random_color.dart';

RandomColor _randomColor = RandomColor();

Color _color = _randomColor.randomColor(
  colorHue: ColorHue.multiple([ColorHue.red, ColorHue.blue])
);

Get highly saturated colors:

import 'package:random_color/random_color.dart';

RandomColor _randomColor = RandomColor();

Color _color = _randomColor.randomColor(
  colorSaturation: ColorSaturation.highSaturation
);

Get light colors:

import 'package:random_color/random_color.dart';

RandomColor _randomColor = RandomColor();

Color _color = _randomColor.randomColor(
  colorBrightness: ColorBrightness.light
);
