Check your dependencies. That is an add-on library which must be included explicitly.

Hi All,

Good Day!

I'm new in GWT and I'm going through documentation and JSInterop. I'm facing issues with implementing chart.js using JSInterop. Can anyone guide me on how to resolve and keep things working? I am facing an error - "The import elemental2 cannot be resolved"

code is - 
package chartjs;

import elemental2.dom.HTMLCanvasElement; => facing error on this line
import jsinterop.annotations.JsPackage;
import jsinterop.annotations.JsType;

@JsType(isNative = true, namespace = JsPackage.GLOBAL)
public class Chart {

    public Chart(HTMLCanvasElement canvasElement, ChartConfiguration configuration) {
    }
}
