tinycolor #

TinyColor is a small library for Flutter color manipulation and conversion

A port of tinycolor2 by Brian Grinstead

Getting Started #

A tinycolor receives a Color as parameter.

import 'package:tinycolor/tinycolor.dart';

final TinyColor = TinyColor(Colors.green);

From a Hex String #

The package uses Pigment by Bregy Malpartida Ramos to convert strings to Color


From RGB int values #

TinyColor.fromRGB(r: 255, g: 255, b:255);

From HSL color #

HslColor color = HslColor(h: 250, s: 57, l: 30);

From HSV color #

HSVColor color = HSVColor(h: 250, s: 57, v: 30);

Properties #

color #

Returns de flutter Color after operations

final Color color = TinyColor(Colors.white).color;

Methods #

getBrightness #

Returns the perceived brightness of a color, from 0-255, as defined by Web Content Accessibility Guidelines (Version 1.0).

TinyColor.fromString("#ffffff").getBrightness(); // 255
TinyColor.fromString("#000000").getBrightness(); // 0

isLight #

Return a boolean indicating whether the color's perceived brightness is light.

TinyColor.fromString("#ffffff").isLight(); // true
TinyColor.fromString("#000000").isLight(); // false

isDark #

Return a boolean indicating whether the color's perceived brightness is dark.

TinyColor.fromString("#ffffff").isDark(); // false
TinyColor.fromString("#000000").isDark(); // true

getLuminance #

Return the perceived luminance of a color, a shorthand for flutter Color.computeLuminance


setAlpha #

Sets the alpha value on the current color.

final color = TinyColor(Colors.red).setAlpha(10);

setOpacity #

Sets the opacity value on the current color.

final color = TinyColor(Colors.red).setOpacity(0.5);

Color Modification #

These methods manipulate the current color, and return it for chaining. For instance:


lighten #

lighten: function(amount = 10) -> TinyColor. Lighten the color a given amount, from 0 to 100. Providing 100 will always return white.


brighten #

brighten: function(amount = 10) -> TinyColor. Brighten the color a given amount, from 0 to 100.


darken #

darken: function(amount = 10) -> TinyColor. Darken the color a given amount, from 0 to 100. Providing 100 will always return black.


tint #

Mix the color with pure white, from 0 to 100. Providing 0 will do nothing, providing 100 will always return white.


shade #

Mix the color with pure black, from 0 to 100. Providing 0 will do nothing, providing 100 will always return black.


desaturate #

desaturate: function(amount = 10) -> TinyColor. Desaturate the color a given amount, from 0 to 100. Providing 100 will is the same as calling greyscale.


saturate #

saturate: function(amount = 10) -> TinyColor. Saturate the color a given amount, from 0 to 100.


greyscale #

greyscale: function() -> TinyColor. Completely desaturates a color into greyscale. Same as calling desaturate(100).


spin #

spin: function(amount = 0) -> TinyColor. Spin the hue a given amount, from -360 to 360. Calling with 0, 360, or -360 will do nothing (since it sets the hue back to what it was before).


// spin(0) and spin(360) do nothing

Common operations #

clone #

clone: function() -> TinyColor. Instantiate a new TinyColor object with the same color. Any changes to the new one won't affect the old one.

final color1 = new TinyColor(Colors.red);
final color2 = color1.clone();
