It sounds like you’re referring to a course (likely on Udemy or similar) titled something like:

List<User> get users => _users; bool get isLoading => _isLoading; else throw Exception("Failed to load users")

// viewmodels/user_viewmodel.dart import 'package:flutter/material.dart'; import '../models/user.dart'; import '../repositories/user_repository.dart'; class UserViewModel extends ChangeNotifier final UserRepository _repository = UserRepository(); List<User> _users = []; bool _isLoading = false;

Future<void> fetchUsers() async _isLoading = true; notifyListeners(); _users = await _repository.getUsers(); _isLoading = false; notifyListeners(); void main() =&gt

// repositories/user_repository.dart import '../models/user.dart'; import '../services/api_service.dart'; class UserRepository final ApiService _api = ApiService(); Future<List<User>> getUsers() async final data = await _api.fetchUsers(); return data.map((json) => User.fromJson(json)).toList();
