Which OS ?

Both

Version

Which versions are you using:

• react-native-swiper v1.5.13 (my fork)
• react-native v0.57

Discussion:

Regarding PR: https://github.com/facebook/react-native/commit/ef7e99c which is landing in RN 0.57 release soon. Can we make use of the new snapToOffsets for react-native-swiper?

Quoting from PR:

Summary:

• Added snapToOffsets prop to ScrollView. Allows snapping at arbitrary points.

• Fixed pagingEnabled not being overridden by snapToInterval on iOS.

• Fixed Android requiring pagingEnabled to be defined alongside snapToInterval.

• Added support for decelerationRate on Android.

• Fixed snapping implementation. It was not calculating end position correctly at all (velocity is not a linear offset).

  • Resolves #20155

• Added support for new content being added during scroll (mirrors existing functionality in vertical ScrollView).

• Added support for snapToInterval.

  • Resolves #19552

Start by reviewing react-native-swiper's current ScrollView snapping behavior and the linked React Native 0.57 change for snapToOffsets and snapToInterval. Determine the intended behavior on both iOS and Android; done should mean the swiper uses the new APIs correctly without regressing existing snapping behavior.
