I went down the rabbit hole to find how to obtain proper node handles and host instances for Shadow Node Wrapper.
I tested the following components:

findNodeHandle()always returns the correct handle on a refgetScrollableNode()always returns a number handle and it's the correct handle (same asfindNodeHandle())findHostInstance_DEPRECATED()always throws on some components, i.e.ViewgetNativeScrollRef()always returns a result offindHostInstance_DEPRECATED()on a ref, iffindHostInstance_DEPRECATED()on the ref doesn't throw (seeScrollViewandFlatList) or an object with__internalInstanceHandleif it throws (seeFlashListorSectionList).__internalInstanceHandle.stateNode.node.findHostInstance_DEPRECATED()doesn't throw on a ref if ref has_reactInternalsproperty.getScrollRef()andgetScrollResponder()methods aren't necessary to obtain the ShadowNodeWrapper.Proposed solution:
findNodeHandleon the ref.__internalInstanceHandleprop. If it does, return it.getNativeScrollRef()method. If it does, returngetNativeScrollRef().__internalInstanceHandle._reactInternalsprop. If it does, returnfindHostInstanceDeprecated().__internalInstanceHandle.Web results

getScrollableNode()returns an actionable ref (i.e. - one that hasscrollTomethod). On components likeSectionListthis is the way of obtaining the actionable ref.getScrollableNode()is not defined on every list component, i.e.SectionList.getNativeScrollRef()always provides an actionable ref if defined.findNodeHandleis an identity function.Proposed solution:
getScrollableNode()method. If it does, returngetScrollableNode().getNativeScrollRef()method. If it does, returngetNativeScrollRef().Test plan
