>> **Note:** Images have specific stretch options (`none`, `aspectFit`, `aspectFill`). At the same time the icon fonts are having `font-size` which can control the size of our font. If you want to set the size of your icon through the `font-size` property then set `stretch` property to `none`. Any other values of the stretch property (including the default one) will cause the icon to be streched by measuring the image (or if there is no sizes set, the parent layout in whcih the image is nested).
