📝 Encrypted Logging Package (Flutter / Dart)

A lightweight, modular logging system for Flutter and Dart applications that supports:

• ✅ Local storage via IndexedDB (using idb_shim)
• 🔒 Encryption using AES (via encrypt)
• 🌐 WebSocket real-time logging
• ☁️ HTTP blob upload support
• 📦 Built for web-first apps with expandability for mobile support

---

📦 Installation

Add the following dependencies to your pubspec.yaml:

🧱 Architecture Overview

• This package is structured with clean architecture principles:
• EncryptionService: Handles AES encryption/decryption.
• LogEntry: Data model with encrypted log message.
• Log: Domain entity.
• LocalDatabase: IndexedDB wrapper for storing logs.
• HTTPHandler: Uploads logs as files to a remote server.
• WebSocketClient: Sends logs over WebSocket.
• LogUseCase: Orchestrates log flow (store, encrypt, send).
• LoggerFacade: One-stop interface to log messages.

🚀 Usage

1. Initialize the logger final logger = await LoggerFacade.initialize( 'ws://your-websocket-url', true, // encryption enabled );
2. await logger.log("Hello, this is a test log!");
