Building a Scalable To-Do App in Flutter Using Provider & Local Storage

Introduction: Beginners often create simple apps without considering scalability or maintainability. In this guide, we’ll build a professional, production-ready To-Do app using Riverpod for state management, Hive for persistent storage, and clean architecture principles. Step 1 Setup Dependencies dependencies: flutter: sdk: flutter flutter_riverpod: ^2.3.6 hive: ^2.2.3 hive_flutter: ^1.1.0 Step 2 Project Structure (Clean Architecture) lib/ ├─ main.dart ├─ models/ │ └─ task.dart ├─ providers/ │ └─ task_provider.dart ├─ services/ │ └─ task_service.dart ├─ screens/ │ └─ todo_home.dart This separation makes the app scalable, testable, and maintainable. Step 3 Create the Task Model import 'package:hive/hive.dart'; part 'task.g.dart'; @HiveType(typeId: 0) class Task extends HiveObject { @HiveField(0) String title; @HiveField(1) bool completed; Task({required this.title, this.completed = false}); } Use build_runner to generate Hive adapters: flutter pub run build_runner build Step 4 Create Ta
