Methods

adjustContrast({required Color on, required double target, int maxIterations = 1000, double epsilon = 0.1}) → Color

Available on Color, provided by the ZetaColorExtensions extension

Adjusts the color to a specific contrast target.
apply({ZetaContrast contrast = ZetaContrast.aa, Brightness brightness = Brightness.light}) → ZetaPureColorSwatch
Creates a copy of the current ZetaColorSwatch with potential modifications based on the provided contrast and brightness.
blend(Color input, [int amount = 10]) → Color

Available on Color, provided by the ZetaColorExtensions extension

Blend in the given input Color with a percentage of alpha.
blendAlpha(Color input, [int alpha = 0x0A]) → Color

Available on Color, provided by the ZetaColorExtensions extension

Blend in the given input Color with an alpha value.
brighten([int amount = 10]) → Color

Available on Color, provided by the ZetaColorExtensions extension

Brightens the color with the given integer percentage amount. Defaults to 10%.
computeLuminance() → double
Returns a brightness value between 0 for darkest and 1 for lightest.
inherited
contrastRatio(Color b) → double

Available on Color, provided by the ZetaColorExtensions extension

Calculates the contrast ratio between the current color and the given color b.
darken([int amount = 10]) → Color

Available on Color, provided by the ZetaColorExtensions extension

Darkens the color with the given integer percentage amount. Defaults to 10%.
ensureAccessibility({required Color on, ZetaContrast standard = ZetaContrast.aa}) → Color

Available on Color, provided by the ZetaColorExtensions extension

Adjusts the current color to meet the specified accessibility standard standard when set against the on color.
generateSwatch({int primary = kZetaSwatchPrimaryIndex, Map<int, double> targetContrasts = kZetaSwatchTargetContrasts, Color background = ZetaColorBase.white, bool adjustPrimary = true}) → Map<int, Color>

Available on Color, provided by the ZetaColorExtensions extension

Generates a color swatch for this color. A color swatch is a map with integer keys indexing to Color objects, typically used for design themes.
getShadeColor({int shadeValue = 15, bool lighten = true, bool keepBlack = true, bool keepWhite = true}) → Color

Available on Color, provided by the ZetaColorExtensions extension

The getShadeColor extension is used to make a color darker or lighter, the shadeValue defines the amount in % that the shade should be changed.
lighten([int amount = 10]) → Color

Available on Color, provided by the ZetaColorExtensions extension

Lightens the color with the given integer percentage amount. Defaults to 10%.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
shade(int number) → Color

inherited
withAlpha(int a) → Color
Returns a new color that matches this color with the alpha channel replaced with a (which ranges from 0 to 255).
inherited
withBlue(int b) → Color
Returns a new color that matches this color with the blue channel replaced with b (which ranges from 0 to 255).
inherited
