SweepSteps class Null safety

Construct a new SweepSteps that progresses from one color to the next in hard steps as opposed to smooth transitions by way of duplicating colors and stops.

See Steps for more information.

SweepSteps({double softness = 0.0, required List<Color> colors, List<double>? stops, TileMode tileMode = TileMode.clamp, AlignmentGeometry center = Alignment.center, double startAngle = 0.0, double endAngle = math.pi * 2, GradientTransform? transform})
A Steps gradient differs from a standard 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. [...]


asGradient SweepGradient
Resolve these Steps to its smooth Gradient counterpart by colors and stops duplication, considering softness.
read-only, override
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. [...]
colors List<Color>
The colors the gradient should obtain at each of the stops. [...]
final, inherited
endAngle double
The startAngle is just as described by SweepGradient.startAngle: [...]
hashCode int
The hash code for this object. [...]
read-only, override
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
softness double
An incredibly small double to provide as an additive for each second entry when duplicating stops for this Steps. [...]
final, inherited
startAngle double
The startAngle is just as described by SweepGradient.startAngle: [...]
steppedColors List<Color>
A duplicated list of colors by CopyColors.
read-only, inherited
steppedStops List<double>
A duplicated list of stops by CopyStops (which may be null, in which case stopsOrImplied is employed). [...]
read-only, inherited
stops List<double>?
A list of values from 0.0 to 1.0 that denote fractions along the gradient. [...]
final, inherited
tileMode TileMode
How these Steps should tile the plane beyond the region before its starting stop and after its ending stop. [...]
final, inherited
transform GradientTransform?
The transform, if any, to apply to the gradient. [...]
final, inherited


copyWith({double? softness, List<Color>? colors, List<double>? stops, TileMode? tileMode, AlignmentGeometry? center, double? startAngle, double? endAngle, GradientTransform? transform}) SweepSteps
📋 Returns a new copy of this SweepSteps with any provided optional parameters overriding those of this.
createShader(Rect rect, {TextDirection? textDirection}) Shader
Resolve these Steps to its smooth Gradient counterpart, then use that gradient's createShader() method. [...]
lerpFrom(Gradient? a, double t) Gradient?
Linearly interpolates from another Gradient to this. [...]
lerpTo(Gradient? b, double t) Gradient?
Linearly interpolates from this to another Gradient. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
scale(double factor) SweepSteps
Returns a new SweepSteps with its colors scaled by the given factor. Since the alpha channel is what receives the scale factor, 0.0 or less results in a gradient that is fully transparent.
toString() String
A string representation of this object. [...]


operator ==(Object other) bool
The equality operator. [...]

Static Methods

lerp(SweepSteps? a, SweepSteps? b, double t) SweepSteps?
Linearly interpolate between two SweepStepss. [...]
