findRenderObjectElement static method

RenderObjectElement? findRenderObjectElement(Element element)

Recursively searches for a RenderObjectElement in the element tree.

This utility method traverses the element tree starting from element, returning the first RenderObjectElement found (depth-first search). Returns null if no RenderObjectElement is found.

This is commonly used when attaching child render objects to their parents, as the child widget may not directly produce a render object (e.g., when wrapped in a StatelessWidget).

Implementation

static RenderObjectElement? findRenderObjectElement(Element element) {
  if (element is RenderObjectElement) {
    return element;
  }
  for (final child in element.children) {
    final found = findRenderObjectElement(child);
    if (found != null) {
      return found;
    }
  }
  return null;
}
