GradientTween class
An interpolation between two Gradients.
This class specializes the interpolation of Tween<Gradient> to use Gradient.lerp and bespoke IntermediateGradients.
See Tween for a discussion on how to use interpolation objects.

An interpolation between two
Gradients.
Properties
- begin ↔ Gradient?
-
The value this variable has at the beginning of the animation.

- end ↔ Gradient?
-
The value this variable has at the end of the animation.

Methods
-
animate(
Animation< double> parent) → Animation<Gradient?> -
Returns a new Animation that is driven by the given animation but that
takes on values determined by this object.
inherited
-
chain(
Animatable< double> parent) → Animatable<Gradient?> -
Returns a new Animatable whose value is determined by first evaluating
the given parent and then evaluating this object.
inherited
-
evaluate(
Animation< double> animation) → Gradient? -
The current value of this object for the given Animation.
inherited
-
lerp(
double t) → Gradient -
Return the value this variable has at the given animation clock value
t.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
transform(
double t) → Gradient? -
Returns the interpolated value for the current value of the given animation.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
