drawVertices abstract method

Draws a set of Vertices onto the canvas as one or more triangles.

The Paint.color property specifies the default color to use for the triangles.

The Paint.shader property, if set, overrides the color entirely, replacing it with the colors from the specified ImageShader, Gradient, or other shader.

The blendMode parameter is used to control how the colors in the vertices are combined with the colors in the paint. If there are no colors specified in vertices then the blendMode has no effect. If there are colors in the vertices, then the color taken from the Paint.shader or Paint.color in the paint is blended with the colors specified in the vertices using the blendMode parameter. For the purposes of this blending, the colors from the paint parameter are considered the source, and the colors from the vertices are considered the destination. BlendMode.dst ignores the paint and uses only the colors of the vertices; BlendMode.src ignores the colors of the vertices and uses only the colors in the paint.

All parameters must not be null.
