Part 1: Get Data

1. Install dio into your project:

flutter pub add dio

2. Create a folder named services, inside it create a file called pets_services.dart.
3. Import dio package in pets_services.dart.

import "package:dio/dio.dart";

4. Create a new DioClient class and initialize a new dio instance.
5. Create a function to get the list of pets and name it getPets.
6. Our endpoint is:

Get, https://coded-pets-api-crud.herokuapp.com/pets

8. Dont forget to ass async and await
9. Store the response of the request in a Response object.
10. In your PetsProvider, create a new function that calls getPets .
11. Make the button in the home_page call the provider function.
12. Print the response in the debug console.

Part 2: Use the data

11. Add the following packages flutter pub add json_serializable , build_runner
12. Go to the pets model and add this code before the class

import 'package:json_annotation/json_annotation.dart';

part 'pet.g.dart';
@JsonSerializable()

13. Run this in terminal flutter pub run build_runner build
14. Add the following code in the pet model

factory Pet.fromJson(Map<String, dynamic> json) => _$PetFromJson(json);
  Map<String, dynamic> toJson() => _$PetToJson(this);

15. In pets_services.dart save the response in a list of pets and convert from Json to pet List<Pet> pets =(res.data as List).map((pet) => Pet.fromJson(pet)).toList();
16. Add try and catch in case of Dio Error try{...}on DioError catch(error){...}
17. Change return type to List, fix the function so that it returns a future list of pets
18. Finally fix the provider as well by adding async and await
