See RenderView for an example of how this function is used.

Implementation 

void scheduleInitialPaint(ContainerLayer rootLayer) {
  assert(rootLayer.attached);
  assert(attached);
  assert(parent is! RenderObject);
  assert(!owner._debugDoingPaint);
  assert(isRepaintBoundary);
  assert(_layer == null);
  _layer = rootLayer;
  assert(_needsPaint);
  owner._nodesNeedingPaint.add(this);
}
