Description
Hi,
I must be misunderstanding something basic and I apologize if this is the case, but I spent a few hours trying to get to this.state of the component that renders Swiper on swipe. I am doing this to keep history of swiping.
<Swiper style={swiperStyles.wrapper} height={160}
onMomentumScrollEnd ={this._onMomentumScrollEnd}
what am I doing wrong and how can I do what I need to be done?
Thanks in advance.

Research direction
Start with the Swiper component's onMomentumScrollEnd callback and the caller's _onMomentumScrollEnd handler. Reproduce the undefined this.state behavior in a React Native example, then determine whether the callback behavior needs a code change or clearer documentation. Done means the handler's state access behavior is established and covered by an appropriate check or explanation.
