tinycolor 1.0.3

Flutter Color manipulation and conversion, ported from JS tinycolor2

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);

Now you can also use the package to extend the native Color class with all the same features, but simpler. To use extension update, make sure to change envieronment sdk version in pubspec like this: sdk: ">=2.6.0 <3.0.0"

From a Hex String #

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

TinyColor.fromString('#FE5567');

From RGB int values #

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

From HSL color #

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

From HSV color #

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

From Flutter's Color #

TinyColor tinyColor = Colors.blue.toTinyColor();

Properties #

color #

Returns the 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
// or with Color extension
Colors.grey.brightness;  // 127

isLight #

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

TinyColor.fromString("#ffffff").isLight(); // true
TinyColor.fromString("#000000").isLight(); // false
// or with Color extension
Colors.white.isLight;  // true

isDark #

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

TinyColor.fromString("#ffffff").isDark(); // false
TinyColor.fromString("#000000").isDark(); // true
// or with Color extension
Colors.white.isDark;  // false

getLuminance #

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

TinyColor.fromString("#ffffff").getLuminance();
// or with Color extension
Colors.white.luminance;

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:

TinyColor(Colors.red).lighten().desaturate().color;
// or with Color extension
Colors.red.lighten().desaturate();

lighten #

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

TinyColor(Colors.red).lighten().color;
TinyColor(Colors.red).lighten(100).color;
// or with Color extension
Colors.red.lighten(50);

brighten #

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

TinyColor(Colors.black).brighten().color;
// or with Color extension
Colors.black.brighten(50);

darken #

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

TinyColor(Colors.red).darken().color;
TinyColor(Colors.red).darken(100).color;
// or with Color extension
Colors.red.darken(50);

tint #

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

TinyColor(Color.red).tint().color;
TinyColor(Color.red).tint(100).color;
// or with Color extension
Colors.red.tint(50);

shade #

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

TinyColor(Colors.red).shade().color;
TinyColor(Colors.red).shade(100).color;
// or with Color extension
Colors.red.shade(50);

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.

TinyColor(Colors.red).desaturate().color;
TinyColor(Colors.red).desaturate(100).color;
// or with Color extension
Colors.red.desaturate(50);

saturate #

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

TinyColor(Colors.red).saturate().color;
// or with Color extension
Colors.red.saturate(50);

greyscale #

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

TinyColor(Colors.red).greyscale().color;
// or with Color extension
Colors.red.greyscale;

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).

TinyColor(Colors.red).spin(180).color;
// or with Color extension
Colors.red.spin(180);

// spin(0) and spin(360) do nothing
TinyColor(Colors.red).spin(0).color;
TinyColor(Colors.red).spin(360).color;

compliment #

compliment: function() -> TinyColor. Returns the Complimentary Color for dynamic matching.

TinyColor(Colors.red).compliment().color;
// or with Color extension
Colors.red.compliment;

mix #

mix: function(toColor, amount = 10) -> TinyColor. Blends the color with another color a given amount, from 0 - 100, default 50.

TinyColor(Colors.red).mix(TinyColor(Colors.yellow, 20)).color;
// or with Color extension
Colors.red.mix(Colors.yellow, 20);

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();
color2.setAlpha(20);
