ImageElement 构造函数

ImageElement(
  1. {String? src,
  2. int? width,
  3. int? height}
)

实现

factory ImageElement({String? src, int? width, int? height}) {
  ImageElement e = JS<ImageElement>(
      'returns:ImageElement;creates:ImageElement;new:true',
      '#.createElement(#)',
      document,
      "img");
  if (src != null) e.src = src;
  if (width != null) e.width = width;
  if (height != null) e.height = height;
  return e;
}
