React Native Flatlist Scroll issue










2















I am new to react native. i am using flatlist for loading 10000 items. i am using lazy loading for getting items. problem is when i rendered more items and i tried to scroll to upper direction, it scrolls before rendering the items. is there any solution..? or can we controll the speed of the scroll..?



<FlatList
ref="flatList"
data=this.state.skus_list
keyExtractor=(item, index) => `post__$item.id`
renderItem = this.renderItem
ListFooterComponent=this.renderFooter
ListEmptyComponent=this.onEmptyData
onEndReached=this.loadMoreSkus
initialNumToRender=20
maxToRenderPerBatch=20
extraData=this.props.orders.orders

/>

          Use methods onScroll and onScrollAnimationEnd



          Fetch data in onScroll Method.



          Update state on onScroll or onScrollAnimationEnd
