          renderSwipePage={this.renderPage}
          isLoop={true}
          animation={(animatedValue, toValue, gestureState) => {
            let velocity = Math.abs(gestureState.vx);
            let baseDuration = 300;
            let duration = (velocity > 1) ? 1 / velocity * baseDuration : baseDuration;
            
            return Animated.timing(animatedValue,
              {
                toValue: toValue,
                duration: duration,
                easing: Easing.out(Easing.exp),
