qr_scanner_kit 0.1.1

A ready-to-use QR scanner screen and viewfinder overlay built on mobile_scanner, with torch, camera switching, and a simple scan callback.

0.1.1

• Rewrite the README. The install section now uses flutter pub add qr_scanner_kit.

0.1.0

• Initial release.
• Extracted the Rocketbot app's QR scanning into a reusable package: QrScanner, BarcodeOverlay, and ScanGate, built on mobile_scanner ^7.
• QrScanner is a full-screen scanner with a camera preview, torch control, and front/back camera switching.
• Every capture goes through a single scan-result path (one barcode stream subscription), fixing the app's old widget that handled results twice through both onDetect and a stream listener.
• Lifecycle-safe disposal ordering: the widget stops the subscription, then disposes the controller, and the controller is never disposed from the scan handler. Camera stop errors are swallowed instead of surfacing as unhandled exceptions.
• BarcodeOverlay.scale now preserves every configured value (border, radius, cut-out, and offset) instead of resetting them to defaults.
• onScan has one-shot semantics: at most one value per widget lifetime. popOnScan: false keeps the screen open but reports no further barcodes.
• An injected MobileScannerController has its autoStart setting respected; the widget still manages start/stop and takes ownership by disposing it.
• BarcodeOverlay is derived from OverlayShape in ai_barcode_scanner 5.2.2 (Apache-2.0); attribution is documented in the README and THIRD_PARTY_NOTICES.
