no setter, override

alpha → int

The alpha channel of this color in an 8 bit value.

no setter, override

b → double

The blue channel of this color.

no setter, override

blue → int

The blue channel of this color in an 8 bit value.

no setter, override

colorSpace → ColorSpace

The color space of this color.

hashCode → int

The hash code for this object.

no setter, inherited

opacity → double

The alpha channel of this color as a double.

no setter, override

r → double

The red channel of this color.

no setter, override

red → int

The red channel of this color in an 8 bit value.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

Methods

$getProperty(Runtime runtime, String identifier) → $Value?

Get a property by identifier on this instance

$getRuntimeType(Runtime runtime) → int

Index of the class Type in the runtime dictionary. By definition can change from run to run, so it's customary to use Runtime.lookupType in implementations.

$setProperty(Runtime runtime, String identifier, $Value value) → void

Set a property by identifier on this instance to value

computeLuminance() → double

Returns a brightness value between 0 for darkest and 1 for lightest.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toARGB32() → int

Returns a 32-bit value representing this color.

override

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).

override

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).

override

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).

override

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).

override

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).

override

withValues({double? alpha, double? red, double? green, double? blue, ColorSpace? colorSpace}) → Color

Returns a new color with the provided components updated.

override

Operators

operator ==(Object other) → bool

The equality operator.
