onChild property
final
The callback that will be called whenver a child element is found.
Please note that all children and grandchildren etc. will trigger this method, it's easy to check whether an element is direct child:
BuildOp(
onChild: (childMeta) {
if (!childElement.element.parent != parentMeta.element) return;
childMeta.doSomethingHere;
},
);
Implementation
final void Function(BuildMetadata childMeta) onChild
