DomRectReadOnly 构造函数

DomRectReadOnly(
  1. [num? x,
  2. num? y,
  3. num? width,
  4. num? height]
)

实现

factory DomRectReadOnly([num? x, num? y, num? width, num? height]) {
  if (height != null) {
    return DomRectReadOnly._create_1(x, y, width, height);
  }
  if (width != null) {
    return DomRectReadOnly._create_2(x, y, width);
  }
  if (y != null) {
    return DomRectReadOnly._create_3(x, y);
  }
  if (x != null) {
    return DomRectReadOnly._create_4(x);
  }
  return DomRectReadOnly._create_5();
}
