Seems you just have to evaluate the gestureState and return true or false depending on whether you want the gesture to be recognised or not, eg to get it to swipe open right menu only if dragging from the last 30 points:

responderNegotiate={(evt, gestureState) => {
  return Dimensions.get('window').width - (gestureState.moveX - gestureState.dx) < 30;
}}
