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
