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 = Colors.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: Takes an integer as argument and returns a color shade based on that number.
toARGB32() → int: Returns a 32-bit value representing this color.
inherited
toString() → String: A string representation of this object.
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
withGreen(int g) → Color: Returns a new color that matches this color with the green channel replaced with g (which ranges from 0 to 255).
inherited
withLightness(double percentage) → Color: Available on Color, provided by the ZetaColorExtensions extension
Applies lightness percentage to color.
withOpacity(double opacity) → Color: Returns a new color that matches this color with the alpha channel replaced with the given opacity (which ranges from 0.0 to 1.0).
inherited
withRed(int r) → Color: Returns a new color that matches this color with the red channel replaced with r (which ranges from 0 to 255).
inherited
withValues({double? alpha, double? red, double? green, double? blue, ColorSpace? colorSpace}) → Color: Returns a new color with the provided components updated.
