useNativeDriver: true require <Animated.X> series components. https://reactnative.dev/blog/2017/02/14/using-native-driver-for-animated#how-do-i-use-this-in-my-app

Caveats of useNativeDriver: true:

1. support non-layout properties, such as transform and opacity, but not Flex box and position properties.
2. work with direct events, but not bubbling event(e.g. PanResponder).

PanResponder's onPanResponderMove listener receives a gestureState object as second params, in which dx and dy can be used in Animated.event https://reactnative.dev/docs/animated#event.

onPanResponderMove: (event, gestureState) => {}

onPanResponderMove: Animated.event(
  [
     null,               // raw event arg ignored
     {dx: this._panX}    // gestureState arg
  ],
  { 
    listener: (event, gestureState) => console.log(event, gestureState)
  }, // Optional async listener
)
