1.2.0

• decouple dependencies

1.1.0 - 2025-01-16

• Removed dependency on separate dart_barcode package

• Live Detection Overlay: Green bounding boxes appear instantly when barcodes are detected

• Visual Feedback: Shows barcode location before successful decoding

• Crosshair Guidance: Blue crosshair helps users position camera when no barcode detected

• Clean Interface: Minimalist overlay without text clutter

• User Reassurance: Visual confirmation that detection system is actively working

• Point-of-Sale Mode: ScannerConfig.pointOfSale() - Single scan with haptic feedback

• Continuous Mode: ScannerConfig.continuous() - Multiple scans for inventory use

• Simplified Configuration: Removed complex Fast/Accurate modes for cleaner API

🖥️ Cross-Platform Support:

• macOS Support: Added camera_macos integration alongside Windows support
• Platform Detection: Automatic camera manager selection based on platform
• Native Performance: Platform-optimized camera handling

📊 Enhanced Results:

• Location Data: BarcodeResult now includes precise barcode coordinates
• Confidence Scoring: Detection confidence available (though not displayed by default)
• Better Metadata: Enhanced barcode format and positioning information
• Cleaner separation between public API and internal implementation

🎨 User Interface:

• Split-Screen Example: Camera preview (2/3) + product info panel (1/3)
• Clean Scan History: Simple display without technical clutter
• Modern Design: Professional point-of-sale ready interface
• Responsive Layout: Adapts to different screen sizes

⚡ Performance Optimizations:

• Embedded Assets: All models and libraries bundled efficiently
• Memory Management: Improved detection coordinate tracking
• Real-Time Updates: Smooth overlay rendering with minimal performance impact
• Resource Cleanup: Proper disposal of detection state

🎯 Configuration Examples:

// Point-of-sale: Single scan with haptic feedback
ScannerConfig.pointOfSale()

// Continuous: Multiple scans for inventory
ScannerConfig.continuous()

BREAKING CHANGES - Core Architecture Separation

Major refactoring: Extracted core barcode detection logic into separate weebi_barcode_dart package for better modularity and reusability.

New Architecture

• Core Package: weebi_barcode_dart - Pure Dart barcode detection with FFI interface
• UI Package: weebi_barcode_scanner - Flutter widget layer with camera integration
• Service Package: weebi_openfoodfacts_service - Product information service

Changes Made

• ✅ Extracted embedded dart_barcode logic to external weebi_barcode_dart package
• ✅ Simplified dependency management - no more embedded FFI code
• ✅ Improved modularity - core detection can be used in any Dart/Flutter project
• ✅ Enhanced API consistency between packages
• ✅ Added comprehensive documentation and examples

Migration Guide

No changes required for existing users - the public API remains the same:

BarcodeScannerWidget(
  onBarcodeDetected: (result) {
    print('Detected: ${result.text}');
  },
)

Benefits

• 🎯 Reusable Core: Use barcode detection in any Dart project
• 🏗️ Better Architecture: Clear separation between detection, UI, and services
• 📦 Simplified Dependencies: Cleaner package structure
• 🔧 Framework Agnostic: Core detection works outside Flutter
• 📚 Better Documentation: Each package has focused documentation
