attach method

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

Mark this node 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 first call their inherited attach method, and then attach all their children to the same owner.

Implementation

@override
void attach(PipelineOwner owner) {
  super.attach(owner);
  _delegate._repaint?.addListener(markNeedsPaint);
}
