A production-ready scanner widget that reads QR codes and popular barcodes in real time with a clean camera overlay, precise scan area, and contextual actions. It handles permissions, autofocus, torch, haptics, and returns a parsed result (URL, text, phone, email, Wi-Fi, geo, etc.) with quick actions like Open, Copy, or Scan again. Fully customizable for size, mask/blur, corner radius, colors, icons, and feedback.

Functionality

• Real-time detection of QR + major 1D/2D formats (QR, Code128, EAN-13, UPC-A, PDF417, Data Matrix).

• Configurable scan window (square/rounded), overlay mask, and animated indicator.

• Result sheet with content parsing and actions: open link, dial, compose email/SMS, connect to Wi-Fi, copy to clipboard, share.

• Camera controls: torch toggle, autofocus, pinch-to-zoom (optional), pause/resume, re-scan button.

• Robust permission flow with graceful fallbacks and error states.

• Debounce & duplicate-protection (prevents repeated triggers on the same code).

• Optional sound/vibration/haptic feedback on successful scan.

• Optional “scan from gallery/photo” and cropping for still images.

• Lightweight, device-tested; works in portrait/landscape and supports dark/light themes.

Use Cases

• In-app onboarding and deep linking via QR.

• Retail/warehouse inventory and pick/pack workflows.

• Event tickets, coupons, loyalty cards, and membership passes.

• Payments, check-ins, parcel tracking, and kiosk flows.

• Quick sharing of URLs, contact cards, and Wi-Fi credentials.
