Flatlist ListEmptyComponent Center

  <FlatList
  data={params}
  renderItem={renderItem}
  keyExtractor={(item) => item.unique.toString()}
  ListEmptyComponent={RenderEmpty}
  onEndReached={()=>(<LoadingSpinner/>)}
  contentContainerStyle={{ flexGrow: 1}}

/>


  contentContainerStyle={{ flexGrow: 1}} this will work
