RadialShadedSteps class

Construct a new RadialShadedSteps that progresses from one color to the next in hard steps, each with its own intrinsic "shading," as opposed to smooth transitions by way of "quadruplicating" colors and stops.

Consider RadialSteps for more information.
The difference for FooShadedSteps is that instead of duplicating a color to make it hard step at each transition, each color and stop is laid out according to a softness, shadeFunction and shadeFactor to provide the same effect across four entries instead of only two and allow greater control over the inner appearance of each given step.

Constructors

RadialShadedSteps.new({ColorArithmetic shadeFunction = Shades.withWhite, double shadeFactor = -90, double distance = 0.6, double softness = 0.0, required List<Color> colors, List<double>? stops, AlignmentGeometry center = Alignment.center, double radius = 0.5, AlignmentGeometry? focal, double focalRadius = 0.0, TileMode tileMode = TileMode.clamp, GradientTransform? transform}): A standard Steps gradient differs from the average Gradient in its progression from one color to the next. Instead of smoothly transitioning between colors, Steps have hard edges created by duplicating colors and stops.

Properties

asGradient → RadialGradient: Resolve these Steps to its smooth Gradient counterpart by colors and stops duplication, considering softness.

asNill → Gradient: Available on Gradient, provided by the NillGradients extension
Gradient get asNill => nillify( /* this. */ runtimeType);
no setter

If this is a radial- or sweep-type Gradient, returns this.center. Otherwise the fallback retrun value is Alignment.center.
no setter
center → AlignmentGeometry: The color that correlates to stops entry 0 (the first color) is placed at AlignmentGeometry center, an offset into the (-1,-1) x (1,1) "paintbox" onto which the gradient will be painted.

no setter
hashCode → int: The hash code for this object.
