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.

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

Methods
-
animate(
{required Animation< double> controller, Map<GradientAnimation, dynamic> storyboard = const {}, GradientCopyWith overrideCopyWith = spectrumCopyWith}) → Gradient -
Available on Gradient, provided by the GradientUtils extension
Returns the AnimatedGradient.observe animatedGradient
output from anew AnimatedGradient
constructed bythis
gradient and the provided parameters. -

📋 Returns a new copy of this
LinearSteps

Available on Gradient, provided by the GradientUtils extension
📋 Returns a new copy of thisGradient
with any appropriate optional parameters overriding those ofthis
. -
createShader(
Rect rect, {TextDirection? textDirection}) → Shader -
Resolve these
Steps
to its smoothGradient
counterpart, then use that gradient'screateShader()
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
-
withOpacity(
double opacity) → Gradient -
Returns a new Gradient with each color set to the given opacity.
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.
