we can potentially solve this with childSemanticsDelegate, but it will be equally hacky. I think we need a better way to listen to child semantics subtree |

What would be the better way to do this? We should be careful with delaying things by a frame. This often leads to other problems...

I don't have anything concrete yet. some ideas i have
- maybe semanticsnode can register change listener, this may lead to circular dependency though
- update semantics node from bottom up, this may lead to performance implication as we may calculate node that get throws a way at the end.
- use childSemanticsDelegate to create incomplete fragment with desired property, in this case, gets the label from child semantics and replace it with a incompletefragment with value set to the childSemantics.label.

actually I think build from bottom up may be ok... let me try it

no this is not going to work, the parentsemanticsclip has to be passed from ancestor to bottom. I imagine compute from bottom up will have to keep recalculating geometry

If we really want to do a bottom up, we have to do the semantics update in three pass. 1. update parentdata.(topdown) 2, update geometry.(topdown) 3 builds semantics node(bottom up)
|
closing after discussing offline that we may need to update the semantics optimization pr to rebuild dirty semantics node from bottom up |
|
actually we should at least merge in the test |
