A shader (as used by Paint.shader) that renders a color gradient.

There are two useful types of gradients, created by new Gradient.linear and new Griadent.radial.

Constructors

Gradient()

Creates a Gradient object that is not initialized.

Gradient.linear(List<Point> endPoints, List<Color> colors, [ List<double> colorStops = null, TileMode tileMode = TileMode.clamp ])

Creates a linear gradient from endPoint[0] to endPoint[1]. If colorStops is provided, colorStops[i] is a number from 0 to 1 that specifies where color[i] begins in the gradient. If colorStops is not provided, then two stops at 0.0 and 1.0 are implied. The behavior before and after the radius is described by the tileMode argument.

Gradient.radial(Point center, double radius, List<Color> colors, [ List<double> colorStops = null, TileMode tileMode = TileMode.clamp ])

Creates a radial gradient centered at center that ends at radius distance from the center. If colorStops is provided, colorStops[i] is a number from 0 to 1 that specifies where color[i] begins in the gradient. If colorStops is not provided, then two stops at 0.0 and 1.0 are implied. The behavior before and after the radius is described by the tileMode argument.
