PanResponder.create() API either loses state or has stale state

Description

PanResponder has a bunch of private state. This means it's not safe to re-create during a gesture: that state would be lost. This means that it's important to keep a ref to PanResponder which is what the docs seem to suggest.

However, holding a ref to it is bad because all the props and state captured by handlers will be stale. To fix this, you have to either update parts of that ref manually, or to recreate the PanResponder instance (which, as mentioned earlier, will reset its state — which seems bad).

I think this says that PanResponder.create API is not a good API for Hooks and need to be revisited. E.g. maybe it should be a Hook like usePanResponder(config) which takes care of updating the appropriate event handlers as needed — or maybe implemented with useRef inside. The important part is that the handlers should always be fresh (and capture fresh values), while the internal state of the gesture recognizer should never be destroyed.

Commencez par packages/react-native/Libraries/Interaction/PanResponder.js, en particulier par l’état privé et l’API PanResponder.create décrits dans l’issue, et comparez-les au modèle d’utilisation documenté de PanResponder. Déterminez comment les handlers peuvent recevoir des valeurs actualisées sans détruire l’état du geste ; le travail sera considéré comme terminé lorsqu’une orientation d’API approuvée et le comportement correspondant pour la conservation de l’état et l’actualisation des handlers auront été définis.
