attach method

  1. @override
void attach(
  1. PipelineOwner owner
)
override

Mark this render object as attached to the given owner.

Typically called only from the parent's attach method, and by the owner to mark the root of a tree as attached.

Subclasses with children should override this method to attach all their children to the same owner after calling the inherited method, as in super.attach(owner).

Implementation

@override
void attach(PipelineOwner owner) {
  controller._addVisibleListener(_handleIsVisibleChange);
  if (onRendererCreated != null) {
    onRendererCreated?.call(controller);
  }
  super.attach(owner);
}
