Flutter Modular Micro Frontend Architecture Guide

A comprehensive Flutter project demonstrating a scalable micro frontend architecture using the Flutter Modular framework. This architecture promotes separation of concerns, independent deployment, and team autonomy in large-scale Flutter applications.

🚀 Features

• Modular Architecture: Clean separation of features into independent modules
• Micro Frontend Support: Each feature can be developed and deployed independently
• Scalable Structure: Organized codebase that grows with your application
• Dependency Injection: Built-in dependency management with Flutter Modular
• Feature Isolation: Independent feature development and testing

🏛️ Architecture Overview

This project follows a microfrontend architecture using Flutter Modular, which provides:

• Feature Modules: Self-contained units of functionality
• Lazy Loading: Modules are loaded on-demand
• Dependency Injection: Clean dependency management
• Navigation: Type-safe routing between modules

Core Concepts

1. Modules: Independent units of functionality
2. Routes: Navigation between different modules
3. Binds: Dependency injection system
4. Child Modules: Nested module structure for complex features

📦 Adding a New Feature Module

1. Create a new directory under packages/features/

2. Set up the module structure:

   your_feature/
   ├── lib/
   │   ├── your_feature_module.dart
   │   ├── pages/
   │   └── widgets/
   ├── test/
   └── pubspec.yaml
   

3. Register the module in app_module.dart
