Description
I use swiper datasource that can be dynamic.
When I load swiper with 5 items and reduce it to 2 items and then increase to 3 items only two items are rendered 3rd it blank screen.
This scenario works perfect on ios.
This happens only on android.
I dig a bit and found that ViewPagerAndroid component is actually problem here.
I discovered that if I put key={Math.random()} fix the issue but then I loose animation between items.
I tried to put key={this.children.length} and this doesn't work.
Do you have some suggestion on how to fix this on android to work and to have animations?
I am in trouble as main part of the app is based on this component.
One more thing.
Swiper is part of modal component. When issue occurs and I dismiss modal view and bring it back again it load 3 items correctly. I don't know what happen there but seems like some restart of swiper.
Maybe I can restart swiper somehow but don't know how to do it.
Thanks

Research direction
Start by reproducing the Android scenario in which swiper content changes from five items to two and then three, including the modal dismissal and reopen behavior. Inspect the ViewPagerAndroid integration and compare it with iOS behavior; the work is done when dynamic content renders all items on Android while preserving swipe animations.
