Gradient class
A shader (as used by Paint.shader) that renders a color gradient.
There are several types of gradients, represented by the various constructors on this class.
Constructors
-
Gradient.linear(Offset from, Offset to, List<
Color> colors, [ List< double> colorStops, TileMode tileMode = TileMode.clamp ]) -
Creates a linear gradient from
from
toto
. [...] -
Gradient.radial(Offset center, double radius, List<
Color> colors, [ List< double> colorStops, TileMode tileMode = TileMode.clamp, Float64List matrix4, Offset focal, double focalRadius = 0.0 ]) -
Creates a radial gradient centered at
center
that ends atradius
distance from the center. [...] -
Gradient.sweep(Offset center, List<
Color> colors, [ List< double> colorStops, TileMode tileMode = TileMode.clamp, double startAngle = 0.0, double endAngle = math.pi * 2, Float64List matrix4 ]) -
Creates a sweep gradient centered at
center
that starts atstartAngle
and ends atendAngle
. [...]
