1.3.1

🐛 Bug Fixes

  • Code Generator Fix: Fixed malformed template string in code_generator.dart that caused invalid Dart syntax in generated envied classes, preventing build_runner from succeeding
  • Dart Identifier Sanitization: Enhanced toCamelCase function to sanitize environment variable keys, ensuring generated field names are valid Dart identifiers (handles hyphens, dots, and numeric prefixes)

🔧 Technical Improvements

  • Template Correction: Corrected the static field assignment template from invalid _\${''}Env$className to proper _Env$className reference
  • Identifier Validation: Added logic to replace invalid characters and prefix numeric-starting identifiers with underscore

1.3.0

🎨 Interactive CLI with Colors & Real-time Feedback

  • Colored Output System: Complete CLI colorization with ANSI escape codes for better UX
  • Real-time Progress: Live feedback during build processes with progress indicators
  • Enhanced Error Handling: Contextual error messages with visual cues (✗ errors, ⚠ warnings, ✓ success)
  • Color Control: New --no-color flag to disable colored output for CI/CD environments
  • Unicode Icons: Added visual indicators (→ steps, ⏳ progress, ℹ info, 🔍 debug)

🚀 Performance Optimizations (EnvFileParser)

  • Cache Hit Optimization: O(1) cache access with UnmodifiableMapView (-44% performance improvement)
  • LRU Cache Management: Automatic memory-bounded cache with 100MB limit and eviction
  • Memory Safety: Prevents memory leaks with intelligent cache size management
  • Statistics API: New getCacheStats() method for monitoring cache performance
  • Optimized Quote Handling: Improved parsing performance for quoted values

🧪 Testing & Quality

  • Optimization Tests: 15 new tests for EnvFileParser performance and cache functionality
  • Total Test Coverage: 88 tests (up from 73) covering all new features
  • Cache Performance Tests: Benchmark tests ensuring cache hit speed improvements
  • Memory Management Tests: Tests for LRU eviction and memory limits

🔧 Technical Improvements

  • CliColors Utility: Centralized color management system with automatic ANSI detection
  • CliLogger Class: Enhanced logging with multiple log levels and visual feedback
  • Error Context: Improved error messages with file paths and operation context
  • Backward Compatibility: All changes maintain compatibility with existing projects
  • Code Quality: Better separation of concerns with dedicated CLI utilities

📚 Documentation Updates

  • Color Support: Updated README.md with color output examples
  • Performance Metrics: Added benchmark results and optimization details
  • CLI Usage: Enhanced command documentation with new flags and options

1.2.0

🚀 Performance Optimizations

  • Code Generation: Replaced 150+ sequential string operations with bulk templates (-98% overhead)
  • File Caching: Added intelligent file-level caching with timestamp invalidation (-65-75% on multi-builds)
  • Asset Parallelization: Converted sequential asset processing to parallel execution (+30% on asset-heavy projects)
  • Memory Efficiency: Optimized string buffer usage and reduced memory allocations

🔒 Security Enhancements

  • Random Salt Generation: Each encrypted file now uses unique 128-bit random salt (vs fixed salt)
  • Password Validation: Added minimum 8-character password requirement
  • Enhanced Encryption: Improved AES-256 implementation with better key derivation
  • Security Documentation: Comprehensive security practices added to SECURITY.md

🧪 Testing & Quality

  • Comprehensive Test Suite: Added 73 tests covering all functionality (up from ~20)
  • Crypto Tests: 17 tests for encryption/decryption with various scenarios
  • Asset Tests: 26 tests for asset generation and parallelization
  • Cache Tests: 10 tests for caching functionality
  • Error Handling Tests: 20 tests for edge cases and error conditions

📚 Documentation & Future Planning

  • Future Roadmap: Added prioritized optimization recommendations in README.md
  • Security Best Practices: Detailed encryption and key management guidelines
  • Performance Guidelines: Recommendations for optimal usage patterns

🔧 Technical Improvements

  • Error Handling: Enhanced error messages and graceful failure handling
  • Code Quality: Improved maintainability with better separation of concerns
  • Backward Compatibility: All changes maintain compatibility with existing projects
  • Cross-Platform: Verified compatibility across Windows, macOS, and Linux

1.1.6+1

  • Some changes in README.md file

1.1.6
