constructor()

static event(argMapping, config?) Takes an array of mappings and extracts values from each arg accordingly, then calls setValue on the mapped outputs. e.g. onScroll={Animated.event( [{nativeEvent: {contentOffset: {x: this._scrollX}}}] {listener}, // Optional async listener ) ... onPanResponderMove: Animated.event([ null, // raw event arg ignored {dx: this._panX}, // gestureState arg ]),
