renderObject property
The render object at (or below) this location in the tree.
If this object is a RenderObjectElement, the render object is the one at this location in the tree. Otherwise, this getter will walk down the tree until it finds a RenderObjectElement.
Some locations in the tree are not backed by a render object. In those cases, this getter returns null. This can happen, if the element is located outside of a View since only the element subtree rooted in a view has a render tree associated with it.
Implementation
RenderObject? get renderObject {
Element? current = this;
while (current != null) {
if (current._lifecycleState == _ElementLifecycle.defunct) {
break;
} else if (current is RenderObjectElement) {
return current.renderObject;
} else {
current = current.renderObjectAttachingChild;
}
}
return null;
}
