Color class

General purpse Color class. Represent a color as an ARGB value that can be converted to and from num, hex string, hsl, hsla, rgb, rgba and SVG pre- defined color constant.

Implemented types

Constructors

Color(int rgb, [num? alpha])
Create a color with an integer representing the rgb value of red, green, and blue. The value 0xffffff is the color white #ffffff (CSS style). The rgb value of 0xffd700 would map to #ffd700 or the constant Color.gold, where ff is red intensity, d7 is green intensity, and 00 is blue intensity.
Color.createHsla(num hueDegree, num saturationPercent, num lightnessPercent, [num? alpha])
HSL takes three values. The hueDegree degree on the color wheel; '0' is the least and '100' is the greatest. The value '0' or '360' is red, '120' is green, '240' is blue. Numbers in between reflect different shades. The saturationPercent percentage; where'0' is the least and '100' is the greatest (100 represents full color). The lightnessPercent percentage; where'0' is the least and '100' is the greatest. The value 0 is dark or black, 100 is light or white and 50 is a medium lightness.
Color.createRgba(int red, int green, int blue, [num? alpha])
RGB takes three values. The red, green, and blue parameters are the intensity of those components where '0' is the least and '256' is the greatest.
Color.css(String color)
Creates a new color from a CSS color string. For more information, see developer.mozilla.org/en/CSS/color.
Color.hex(String _argb)
Generate a real constant for pre-defined colors (no leading #).
const
Color.hslaRaw(num hue, num saturation, num lightness, [num? alpha])
The hslaRaw takes three values. The hue degree on the color wheel; '0' is the least and '1' is the greatest. The value '0' or '1' is red, the ratio of 120/360 is green, and the ratio of 240/360 is blue. Numbers in between reflect different shades. The saturation is a percentage; '0' is the least and '1' is the greatest. The value of '1' is equivalent to 100% (full colour). The lightness is a percentage; '0' is the least and '1' is the greatest. The value of '0' is dark (black), the value of '1' is light (white), and the value of '.50' is a medium lightness.

Properties

argbValue → int

Methods

darker(num amount) → Color
lighter(num amount) → Color
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toHexArgbString() → String
Canonical form for color #rrggbb with alpha blending (0.0 == full transparency and 1.0 == fully opaque). If _argb length is 6 it's an rrggbb otherwise it's aarrggbb.
override
toString() → String
A string representation of this object.
override

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

convertToHexString(int r, int g, int b, [num? a]) → String
equal(ColorBase curr, dynamic other) → bool
hexToInt(String hex) → int
