Android
Version
Which versions are you using:
- react-native-swiper v1.5.10?
- react-native v0.46.4
Describe
I'm developing a shopping website. On the goods description page,I used swiper. Goods description page can jump to the shopping cart page (navigator.push) and shopping cart page can jump to the goods description page too (infinite stack). The problem is that when there are more than one swiper in the stack, the code prompts "undefined is not an object" in 'updateIndex' function.

Research direction
Reproduce the Android crash with react-native-swiper v1.5.10 and React Native 0.46.4 by navigating between the goods description and cart pages until multiple swipers are in the stack. Start in the updateIndex function and inspect the reported internals.offset[dir] access. Done means repeated navigation with multiple swiper instances no longer produces the undefined-object error.
