🚀 Introduction

This project implements a robust Model-View-Controller (MVC) architectural pattern using GetX for state management in Flutter. Our goal is to create a scalable, maintainable, and efficient mobile application architecture

🏗 Architectural Pattern

MVC Pattern Overview

The Model-View-Controller (MVC) pattern divides the application into three core components:

Component	Responsibility	Description
Model	Data & Business Logic	- Represents application data - Manages data transformations - Implements business rules
View	User Interface	- Displays data to the user - Captures user interactions - Renders widgets
Controller	Intermediary & Logic	- Handles user input - Coordinates between Model and View - Manages application state

🧩 Key Components

1. Model

class ProductModel {
  final String id;
  final String name;
  final String description;
  final double price;
  final String imageUrl;
  final int stock;

  ProductModel({
    required this.id,
    required this.name,
    required this.description,
    required this.price,
    required this.imageUrl,
    required this.stock,
  });
}

2. Controller

class ProductController extends GetxController {
  final ApiServices _apiServices = ApiServices();

  final RxList<ProductModel> _productList = <ProductModel>[].obs;
  List<ProductModel> get productList => _productList;

  Future<void> getProducts() async {
    //...
  }
}

3. View

class ProductScreen extends StatelessWidget {
  const ProductScreen({super.key});

  @override
  Widget build(BuildContext context) {
    final ProductController productController = Get.find();

    return Scaffold(
      body: Obx(() {
        if (productController.productList.isEmpty) {
          return const LoadingIndicator();
        }

        if (productController.productList.isNotEmpty) {
          return _buildProductWidget();
        }

        return const SizedBox.shrink();
      }),
    );
  }
}
