PR Summary

• Introduction of useRef in SwiperFlatList.tsx
  This enhancement incorporates the useRef hook into SwiperFlatList.tsx, an important file in our project. By utilizing this reference hook, we can access and manage specific properties more efficiently, ultimately improving the responsiveness of the application.

• Configuring viewabilityConfigCallbackPairs and onViewableItemsChanged
  We have set up the aforementioned variables in the useRef hook, which allows the application to track which items are viewable on the screen at any moment. Useful for analytics and optimization, this allows us to better understand user behavior and make data-informed decisions.

• Conditional Setting of flatListProps Based on Device Platform
  We have modified the flatListProps to change the value of viewabilityConfigCallbackPairs and onViewableItemsChanged depending on the user's device platform. It means the application will now function more optimally on different devices offering a much more robust user experience by tailoring its behavior based on the platform.
