nodesNeedingPaint property

Iterable<RenderObject> get nodesNeedingPaint

The RenderObjects which need to be painted in the next flushPaint pass.

RenderObjects marked with RenderObject.isRepaintBoundary are added when they are marked needing paint. Subclasses of PipelineOwner may use them to invalidate caches or otherwise make performance optimizations. Since nodes may be marked for layout at any time, they are best checked during flushPaint.

Marked children of child PipelineOwners are not included here.
