Flutter Infra 🏗️

A comprehensive Flutter package providing clean, type-safe local storage solutions and robust network infrastructure with advanced token management and refresh strategies.

✨ Features

💾 Storage Infrastructure

• 🎯 Multiple Storage Backends: SharedPreferences, FlutterSecureStorage, and Hive support
• 🔐 Security First: Clear separation between normal and secure storage operations
• 🧩 Type Safety: Built-in support for JSON, lists, DateTime, and custom objects
• ⚡ Performance: Optional caching and optimized storage implementations

🌐 Network Infrastructure

• 🚀 Dual HTTP Clients: Built-in support for both dart:io HTTP and Dio implementations
• 🔑 Token Management: Automatic token injection and secure storage integration
• 🔄 Refresh Token Strategy: Configurable token refresh with Strategy design pattern
• 📡 Interceptor System: LoggerInterceptor and TokenInterceptor with extensible design

🔧 Common Features

• 🔧 Dependency Injection: Clean DI support with flexible configuration
• 📱 Cross Platform: Works on iOS, Android, Web, Windows, macOS, and Linux
• 🧪 Fully Tested: Comprehensive test coverage with mock support

🚀 Quick Start

Installation

dependencies:
  flutter_infra: ^0.0.1

Basic Usage

import 'package:flutter_infra/flutter_infra.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Storage operations
  final storageService = await StorageService.create();
  await storageService.setString('username', 'john_doe');
  await storageService.setSecureString('api_token', 'secret_token');
  
  // Network operations  
  final networkService = await NetworkService.create(
    config: NetworkConfig(baseUrl: 'https://api.example.com'),
  );
  final response = await networkService.getJson('/users/profile');
  
  runApp(MyApp());
}

With Authentication

// Create network service with automatic token management
final networkService = await NetworkService.createWithTokenSupport(
  config: NetworkConfig(baseUrl: 'https://api.example.com'),
  tokenManager: DefaultTokenManager(storage: storageService),
);

// Tokens are automatically handled
final userProfile = await networkService.getJson('/protected/profile');

🧩 Key Capabilities

Typed Storage Extensions

// JSON operations with both normal and secure versions
await storageService.setJson('user_profile', userData);
await storageService.setSecureJson('auth_tokens', tokenData);

// DateTime and list operations
await storageService.setDateTime('last_login', DateTime.now());
await storageService.setStringList('interests', ['tech', 'music']);

Smart Network Client

// JSON convenience methods
final users = await networkService.getJson('/users');
await networkService.postJson('/users', jsonBody: newUser);

// Automatic token management and refresh
final profile = await networkService.getJson('/protected/profile');

🏗️ Architecture

Flutter Infra follows a layered architecture with clear separation of concerns:

• Application Layer: Your Flutter app, repositories, and services
• Flutter Infra Layer: StorageService, NetworkService, TokenManager
• Implementation Layer: Storage implementations, network clients, interceptors
• Platform Layer: SharedPreferences, FlutterSecureStorage, Hive, HTTP clients

📱 Example App

Check out the example directory for a complete Flutter app demonstrating:

• Default Usage: Basic storage and network operations
• Common Usage: Token management and API integration
• Advanced Usage: Custom configurations and interceptors

🧪 Testing

dart test

The package includes comprehensive test coverage with unit tests, integration tests, and mock support for testing your own code.
