hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stops → List<double>?
A list of values from 0.0 to 1.0 that denote fractions along the gradient.
final
transform → GradientTransform?
The transform, if any, to apply to the gradient.
