⚠️ BREAKING CHANGES WARNING This version introduces significant architectural changes by replacing the JSON-based storage with RedB (Rust Embedded Database). There is no automatic migration system available. Please ensure you have backed up your data before upgrading, as you will need to manually migrate your existing data to the new format.

Breaking Changes

• Removed JSON-based storage in favor of RedB (Rust Embedded Database)
• Removed ConfigDBModel and related configurations
• Reduced minimum ID length requirement from 9 to 3 characters
• Removed MobileDirectoryManager and directory management abstractions
• Eliminated reactive state management through local_database_notifier
• Modified initialization process to require database name
• Removed Get method with pagination (use GetAll instead)
• Removed Clean and DeepClean methods
• Transitioned to Result-based error handling

Added

• Rust-based core using RedB embedded database
• FFI bridge for native platform integration
• Result type system for robust error handling
• Cross-platform native libraries:
  • Android: .so shared library
  • iOS: .a static library
  • macOS: .dylib dynamic library
• Type-safe database operations
• Simplified initialization system
• Rust-inspired Result types for all operations

Changed

• Simplified API focusing on core CRUD operations
• Updated ID validation requirements
• Migrated to async/await for all database operations
• Enhanced error handling with detailed messages
• Improved cross-platform support
• Streamlined initialization process

Removed

• Complex configuration options
• Directory management system
• Automatic backup functionality
• Pagination support
• Deep cleaning methods
• State management integration
• Automatic encryption
• Block-based storage system

Migration Guide

1. Backup existing data
2. Update initialization code:

   // Old
   await LocalDB.init(
     config: ConfigDBModel(
       maxRecordsPerFile: 2000,
       backupEveryDays: 7,
       hashEncrypt: 'your-16-char-key'
     )
   );
   
   // New
   await LocalDB.init(localDbName: "my_app_db");

3. Update CRUD operations to handle Results:

   // Old
   final user = await LocalDB.GetById('user-123');
      
   // New
   final result = await LocalDB.GetById('user-123');
   result.when(
     ok: (user) => print('Found user: ${user?.data}'),
     err: (error) => print('Error: $error')
   );
