Using a LinearGradient as fill color when building shapes in the Angular Kendo Drawing API

Question

I'm attempting to build a rectangle with a linear gradient fill using code similar to:

const gradient = new LinearGradient({
    stops: [
        new GradientStop({
            color: "gray",
            offset: 0,
            opacity: 0
        }),
        new GradientStop({
            offset: 0.5,
            color: "orange",
            opacity: 0.8
        })]
 });


 const geometry = new GeomRectangle([0, 0], [100, 25]);
 const rect = new Rect(geometry, {
       stroke: { color: "black", width: 1 },
       fill: { color: gradient, opacity: 1 } <- Compile error wants string
 });

However, in the TypeScript FillOptions definition, color is defined as string. I can't find an example in the Kendo docs that describe how this might work. I'd be grateful for any insights.

You can pass the gradient directly to the "fill" option of both a Path or a Rect:

const gradient = new LinearGradient({
        name: "LG1",
        stops: [
            {
                offset: 0,
                color: "gray",
                opacity: 0
            }, {
                offset: 0.5,
                color: "orange",
                opacity: 0.8
            }
        ]
    });


  // Create the square border by drawing a straight path
  const path = new Path({
    stroke: {
      color: "#9999b6",
      width: 2
    },
    fill: gradient
  });

const anotherRect = new RectGeometry(
    new Point(100, 100),
    new Size(50, 50)
  );

  const drawingRect = new Rect(anotherRect, {
    stroke: {
      color: "#9999b6",
      width: 2
    },
    fill: gradient
  });
