scannerpro 1.2.0

Universal Flutter Scanner Pro SDK (francis2408/scanner_pro) with real-time REST API lookup, ML Kit vision AI, and multi-document parsing.

1.2.0

• Multi-Threaded Isolate Processing & ROI Scanning: Offloaded frame byte conversion, luminosity analysis, and sub-region ROI cropping to background workers (IsolateFrameProcessor), reducing CPU consumption by ~50% and frame memory payload by 75%.
• Camera Warm-Up & Adaptive Frame Throttling: Added warmup() hardware pre-loader and options.frameThrottleMs throttling frame analysis to 10 FPS while keeping 60 FPS liquid preview rendering.
• Duplicate Detection Caching: Added configurable duplicate caching window (options.duplicateTimeout, default 1000ms) to eliminate repeated scan callbacks.
• Tap-to-Focus, Zoom Controls & Auto-Zoom: Added tapToFocus(point) with animated focus target rings, 1x/2x/4x quick zoom controls, pinch-to-zoom, and distance auto-zoom.
• Ambient Low-Light Brightness Detection: Added relative luminosity scoring (0.0 to 1.0) and interactive low-light flash recommendation prompt.
• Continuous, Single & Batch (Inventory) Modes: Added ScanStrategy options for single scan, continuous scan, and batch scanning (batchResults session inventory queue).
• Rich Diagnostic ScanResult: ScanResult now includes corners, boundingBox, imageSize, and scanDuration.
• Modular Plugin Architecture: Added ScannerPlugin contract and ScannerPluginRegistry allowing developers to register custom OCR, Document, Face, MRZ, or AI recognizers.

1.1.3

• Pub.dev Metadata & Repository Searchability: Updated pubspec.yaml description and README.md with explicit repository badges (francis2408/scanner_pro), architectural decoupling documentation, and high-throughput benchmark scores.

1.1.2

• Data Fetching Performance & Caching: Added sub-millisecond in-memory LRU cache (_lookupCache) and fast connection reuse pool to ExternalLookupService for instant repeat scan lookups (<0.1ms).

1.1.1

• Dependency Constraint Update: Expanded google_mlkit_commons dependency constraint to >=0.9.0 <0.13.0 to support up-to-date stable versions (0.11.0 & 0.12.0).

1.1.0

• ML Kit Dependency Streamlining: Refactored vision scanning engine to rely exclusively on google_mlkit_commons, removing individual sub-package dependencies.
• Sub-Millisecond Vision Performance: Replaced dynamic regular expressions with static compiled constants and pre-cached camera byte buffers, delivering sub-millisecond parsing latency (down to 13 µs per operation) and up to ~76,900 ops/sec throughput.
• Enriched Document Metadata & Accuracy: Added ISO 3166-1 country name resolution, composite ICAO 7-3-1 checks, age calculations, Aadhaar Verhoeff validation, PAN taxpayer category breakdowns, expanded WMI manufacturer databases (50+ global vehicle makes), and Face Liveness verification.
• Performance Benchmark Test Suite: Added comprehensive unit & throughput benchmark tests (test/performance_benchmark_test.dart).

1.0.9

• Standalone Scanning Engine & Custom Screen Design: Added ScannerController and ScannerCameraPreview widgets to decouple camera lifecycle, ML vision scanning, and stream processing from pre-packaged UI layouts.
• Custom Builder Support: Added UniversalScannerView.builder(...) constructor allowing developers to build custom screen UI designs with full access to scanner functionality.
• Updated documentation and example applications demonstrating custom screen UI design usage.

1.0.8

• README Image Rendering Fix: Updated banner and UI preview graphics in README.md to use GitHub raw image URLs and standard Markdown syntax for pub.dev web rendering compatibility.

1.0.7

• Documentation & Graphics Upgrade: Redesigned README.md with complete feature guides, multi-document scanning matrices, platform setup instructions, and high-resolution visual banner/theme preview image graphics (doc/assets/).
• Primary SDK Export: Added lib/scannerpro.dart entry point for clean library imports (import 'package:scannerpro/scannerpro.dart';).

1.0.6

• Package Payload & Archive Optimization: Added .pubignore to strip IDE cache, gradle wrappers, build trees, and unused workspace files from the published pub package.
• Android Binary Shrinking: Enabled R8 bytecode minification (isMinifyEnabled = true), resource shrinking (isShrinkResources = true), and custom proguard-rules.pro for release builds.
• Removed redundant google_mlkit_commons dependency declaration.

1.0.5

• Binary size optimization: Removed unused transitive packages (google_fonts and cupertino_icons) to streamline package payload.
• Added Android Google Play Services unbundled ML Kit vision model metadata (com.google.mlkit.vision.DEPENDENCIES) to download models dynamically on demand, saving up to ~30 MB APK binary size while keeping 100% scanning functionality intact.

1.0.4

• Added complete UI design and color customization via ScannerUiTheme (ScannerUiTheme.dark, ScannerUiTheme.cyan, ScannerUiTheme.emerald, ScannerUiTheme.amber, and custom themes).
• Configurable viewfinder reticle colors, corner bracket dimensions, laser beam colors, overlay dimming mask, text styling, and visibility toggles on UniversalScannerView.

1.0.3

• Resolved static analysis Pana lint issues (curly_braces_in_flow_control_structures) for 160/160 Pana pub points.
• Added mode enable feature flags (enableAadhaar, enablePan, enablePassport, enableQr, etc.) and enabledModes access control to UniversalScannerView.

1.0.2

• Maintenance release and package updates.

1.0.1

• OSI-approved MIT License and standard SPDX license recognition.
• Comprehensive 100% Dartdoc API documentation for 160/160 Pana pub points.
• Package example app implementation in example/.
• Updated dependency ranges for latest Flutter and Dart SDKs.

1.0.0+1

• Initial release of Scanner Pro cross-platform Flutter application.
• Real-time OCR and Barcode detection powered by Google ML Kit.
• Dynamic REST API lookup pipeline (Open Food Facts, UPC Item DB, Open Library, OpenStreetMap Nominatim, India Post, NHTSA VIN).
• Multiformat document parsing engine:
  • Indian Aadhaar Card (Verhoeff D10 checksum + Secure XML/OCR).
  • Income Tax PAN Card (10-char classification + surname decoding + fuzzy OCR correction).
  • UPI Payment QR (GPay, PhonePe, Paytm, Amazon Pay account details).
  • Passports (ICAO Doc 9303 MRZ checksums + Country API metadata).
  • Driving Licenses (AAMVA PDF417 + US Zippopotam lookup).
