LinearSteps class

Construct a new LinearSteps 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.

Constructors

LinearSteps({double softness = 0.001, required List<Color> colors, List<double>? stops, AlignmentGeometry begin = Alignment.centerLeft, AlignmentGeometry end = Alignment.centerRight, TileMode tileMode = TileMode.clamp, 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.

const

Properties

asGradient → LinearGradient

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

no setter, override

begin → AlignmentGeometry

The color that correlates to stops entry 0 (the first color) is placed at AlignmentGeometry begin and the final stop is placed at end, with all the intermediate colors filling the space between them.

final

colors → List<Color>

The colors the gradient should obtain at each of the stops.

final, inherited

end → AlignmentGeometry

The color that correlates to stops entry 0 (the first color) is placed at AlignmentGeometry begin and the final stop is placed at end, with all the intermediate colors filling the space between them.

final

hashCode → int

The hash code for this object.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

softness → double

An incredibly small double to provide as an additive for each second entry when duplicating stops for this Steps.

final, inherited

steppedColors → List<Color>

A duplicated list of colors by CopyColors.

no setter, inherited

steppedStops → List<double>

A duplicated list of stops by CopyStops (which may be null, in which case stopsOrImplied is employed).

no setter, 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

Methods

copyWith({double? softness, List<Color>? colors, List<double>? stops, AlignmentGeometry? begin, AlignmentGeometry? end, TileMode? tileMode, GradientTransform? transform}) → LinearSteps

📋 Returns a new copy of this LinearSteps 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.

inherited

lerpFrom(Gradient? a, double t) → Gradient?

Linearly interpolates from another Gradient to this.

override

lerpTo(Gradient? b, double t) → Gradient?

Linearly interpolates from this to another Gradient.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

scale(double factor) → LinearSteps

Returns a new LinearSteps 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.

override

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.

override

Static Methods

lerp(LinearSteps? a, LinearSteps? b, double t) → LinearSteps?

Linearly interpolate between two LinearSteps.
