patch function

void patch(Node dom, PulsarNode prev, PulsarNode next)

Implementation

void patch(Node dom, PulsarNode prev, PulsarNode next) {
  // Tipo distinto → reemplazo
  if (prev.runtimeType != next.runtimeType) {
    _replace(dom, createDom(next));
    return;
  }

  // Text
  if (prev is TextNode && next is TextNode) {
    if (prev.value != next.value) {
      (dom as Text).data = next.value;
    }
    return;
  }

  // Element
  if (prev is ElementNode && next is ElementNode) {
    if (prev.tag != next.tag) {
      _replace(dom, createDom(next));
      return;
    }

    final el = dom as Element;

    _patchAttributes(el, prev, next);
    _patchChildren(el, prev.children, next.children);
  }
}
