See below code.

@DesignerProperty(editorType = "choices", 
 defaultValue = "default",
 editorArgs = {"default", "rounded", "rectangular", "oval"})
@SimpleProperty(description = "Set shape for component.")
public void Shape(String shape) {
 // Do what you want to do with the `shape`.

i used this on kotlin but not working.

@DesignerProperty(editorType = "dropdown", defaultValue = "Fit center", editorArgs = ["Center", "Center crop", "Center inside", "Fit center", "Fit end", "Fit start", "Fit XY", "Seam carving", "Scale-to-fit"])
    @SimpleProperty(description = "Sets the scale type of the image.")
    fun ImageScale(scale: String) {
        imageScale = scale

if use this method then i got error to use ;

Just replace the dropdown with choices.
