attach method
- covariant 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(covariant PipelineOwner owner) {
_painter = decoration.createBoxPainter(markNeedsPaint);
super.attach(owner);
}
