Can you try to put warehouse in eval?

<FlatList data={(warehouse)} numColumns={1} keyExtractor={(item) => item.id.toString()} initialNumToRender={16} //debug={true} renderItem={renderItem} updateCellsBatchingPeriod={100} ListFooterComponent={handleFooter} onEndReached={handleLoadMore} onEndReachedThreshold={10} />
