Changelog #

0.2.0 #

analyzeImage now reports unsupportedFormats when none of the requested formats is available on the device, instead of detecting every symbology.
Requesting only ean13 now yields UPC-A symbols as zero-prefixed ean13 results on Android too, matching iOS.
scanOnce settles on the code nearest the scan-window / preview center, matching DetectionMode.once.
requestPermission always resolves to a status on Android: no foreground Activity returns notDetermined, concurrent calls share one request, and a request survives Activity recreation.
The Android camera no longer binds while the app is backgrounded when start resolves mid-initialization; scan-window frames wait for the first layout.
iOS re-resolves the scanning / unsupportedFormats state after a lens switch and holds the metadata delegate weakly.
Fixed vCard parsing dropping the property after a malformed quoted-printable trailing =.
Non-positive DetectionOptions.timeout is treated as null; the widget ignores non-finite zoom in release builds.
Documented codabar's iOS floors and the UPC-A / EAN-13 contract.

Lowered the iOS minimum to 13.0 and raised the Android minimum SDK to 24, matching Flutter 3.44's supported platforms.
analyzeImage now detects codabar from iOS 15.0 (previously gated at 15.4).
Shortened the pubspec description so pub.dev displays it fully.

Initial release.

Live QR / barcode scanning via a native PlatformView (AVFoundation on iOS 15+, CameraX + ML Kit on Android 5.0+).
Out-of-the-box widget: owns its controller, auto-starts, auto-disposes and pauses while the app is in the background.
Declarative CameraOptions / DetectionOptions plus runtime control: torch, linear zoom, lens switching, scan window, focus point, pause/resume, scanOnce, capabilities query.
Preview fit (cover / contain), applied natively; coordinates stay normalized under either fit.
Tap-to-focus (tapToFocus) and placeholderBuilder / errorBuilder / overlayBuilder on the widget.
Detection modes: all, noDuplicates (the default; frame-aware, survives resume) and once (picks the code nearest the scan-window center).
Normalized cross-platform corner coordinates; UPC-A normalization on iOS.
Structured states and errors, current-state snapshot, per-frame stream.
Still-image analysis (QrScanner.analyzeImage) and camera permission API (checkPermission / requestPermission / openAppSettings).
Android ML Kit flavor switch: unbundled (Google Play services) by default; opt into the bundled model with com.koji_1009.app.qr_scanner_view.useBundled=true in gradle.properties.
Typed value parsing (barcode.parsed): Wi-Fi, URL, email, phone, SMS, geo, contact (MECARD / vCard), calendar event, ISBN, product and text — implemented in Dart so both platforms parse identically.
