[SOLVED] Flutter How to change rating from string to a star?

so i am making a movie app using themoviedb.org API and i managed to call the rating but what i get is a idk what it's called maybe a number, and i wanted to change this number or convert this number into a star, 5 if i could (there is like 8,8 rating FYI) and idk how

so here is the code :

Chip(
     backgroundColor: Style.Colors.secondColor,
     label: Text(
     'Rating: ' + movies[index].rating.toString(),
     style: TextStyle(fontFamily: 'Raleway'),
     ),
   ),

here is the full code in case you need it :

import 'package:flutter/material.dart';

import 'package:movie_app_3/bloc/get_movies_bloc.dart';
import 'package:movie_app_3/model/movie.dart';
import 'package:movie_app_3/model/movie_response.dart';
import 'package:movie_app_3/screens/movie_detail_screen/movie_detail_screen.dart';
import 'package:movie_app_3/style/theme.dart' as Style;
