Key-Value Storage Service

An abstract interface for key-value storage within the Flutter News App Full Source Code Toolkit.

This kv_storage_service package defines an abstract interface (KVStorageService) for key-value storage within the Flutter News App Full Source Code Toolkit. This promotes consistency and allows for interchangeable storage implementations (like SharedPreferences, Hive, secure storage, etc.), ensuring that application logic remains decoupled from the underlying storage mechanism. It provides a standardized way to interact with local data, crucial for managing user preferences, authentication tokens, and other application settings.

⭐ Feature Showcase: Flexible & Robust Local Storage

This package offers a comprehensive set of features for managing local key-value data.

🧱 Core Functionality

🚀 Abstract KVStorageService Interface

• KVStorageService: Defines a clear contract for basic key-value operations (read, write, delete) for common data types (String, bool, int, double).
• clearAll Method: Provides a method for efficiently removing all entries from the storage.

🔐 Type-Safe Key Management

• StorageKey Enum: Includes a StorageKey enum to avoid magic strings, promoting type safety and reducing errors. Use the stringValue getter for the actual key string.

🛡️ Standardized Error Handling

• Custom StorageException Hierarchy: Defines a comprehensive set of custom StorageException subclasses (StorageWriteException, StorageReadException, StorageDeleteException, StorageClearException, StorageKeyNotFoundException, StorageTypeMismatchException) to handle specific storage errors. This ensures predictable and consistent error management across the application layers.

💉 Implementation Agnostic

• Interchangeable Implementations: Designed to be implemented by various storage mechanisms (e.g., shared_preferences, hive, flutter_secure_storage), allowing developers to swap storage solutions without altering application logic.

💡 Your Advantage: You get a meticulously designed, production-quality key-value storage interface that simplifies local data management, ensures type safety, provides robust error handling, and allows for flexible storage implementations. This package accelerates development by providing a solid foundation for local data persistence.
