SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires provider, freezed_annotation, json_annotation, equatable, http, shared_preferences, build_runner, freezed, json_serializable, mockito, flutter_lints, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of managing complex application states and separating concerns in Flutter development, leading to more maintainable and testable codebases.

Core Features & Use Cases

Architectural Guidance: Provides a structured approach to building Flutter applications using the Model-View-ViewModel (MVVM) pattern.
State Management: Integrates with provider and ChangeNotifier for reactive state management.
Code Organization: Demonstrates best practices for structuring models, views, viewmodels, and services.
Use Case: Develop a user profile management feature with create, read, update, and delete (CRUD) operations, ensuring a clean separation between UI, business logic, and data handling.

Quick Start

Generate a Flutter user list screen using the MVVM pattern with provider.

FAQPage Schema

How do I separate business logic from UI in Flutter apps?▼

Separate business logic from UI in Flutter by implementing the MVVM pattern, which divides code into models, views, viewmodels, and services for maintainable and testable application structures.

How do I manage state in Flutter using provider and ChangeNotifier?▼

Manage state in Flutter using provider and ChangeNotifier by placing ChangeNotifier in viewmodels to expose reactive state updates, allowing views to listen and respond to data changes automatically.

What is the best way to structure a scalable Flutter app with MVVM?▼

Structure a scalable Flutter app with MVVM by organizing directories into models, views, viewmodels, and services, ensuring clean separation between data fetching, business logic, and UI rendering.

Can I handle data fetching and error handling in a Flutter MVVM architecture?▼

Handle data fetching and error handling in a Flutter MVVM architecture by isolating network requests in services and managing state or error propagation through the viewmodel to the UI layer.

Does the Flutter MVVM pattern support CRUD operations with shared preferences?▼

The Flutter MVVM pattern supports CRUD operations by integrating shared preferences for local storage, managing data persistence through services and updating viewmodels to reflect state changes.

When should I not use the MVVM pattern in Flutter?▼

Avoid the MVVM pattern in Flutter for simple prototypes or small applications where the overhead of separating models, viewmodels, and services outweighs the benefits of maintaining strict architectural boundaries.
