barcode_scanner_plugin 0.2.2

A powerful Flutter plugin for dual-mode barcode scanning. Supports dedicated PDA hardware via Broadcast Intents and smartphone cameras using CameraX and Google ML Kit.

0.2.2

• Improvement: Update camera frame.

0.2.1

• Improvement: Camera UI now provides interactive zoom control (0x–1x linear zoom) for better barcode detection at varying distances.

0.2.0

• Major UI Redesign: Completely redesigned camera scan interface:
  • Transparent scan frame with clipOutRect instead of PorterDuff CLEAR - camera preview shows through the frame area clearly.
  • Blue semi-transparent overlay (#2196F3 at 53% alpha) around the frame for better visual focus.
  • Gradient blur/feather edges using 4 LinearGradients + 4 RadialGradients for a soft transition between overlay and frame.
  • Touch zoom wheel on the right side with visual track, green thumb indicator, and +/- buttons (replaces old SeekBar).
  • Lightning bolt flash icon (yellow when on, white when off) with scale animation feedback.
  • Close button with X icon drawable.
• Performance Optimization:
  • Zero allocations in onDraw() (all Paint objects pre-allocated as fields).
  • postInvalidateOnAnimation() for vsync-aligned rendering instead of invalidate().
  • Reusable RectF and Path to avoid GC churn.
  • Frame analysis throttled to 150ms interval to reduce CPU/battery usage.
  • Scan line early-return optimization when outside visible area.
• Bilingual Documentation: All Kotlin source files now have comprehensive comments in both English and Vietnamese.
• Example App Redesign: Updated example/lib/main.dart with Material 3, loading states, and usage guide.
