Configurable QR and barcode scanning. One call gives you a full-screen scanner, or embed the camera preview inside a screen you designed — your own reticle, live focus and torch control. Results arrive as events rather than a return value.

• A full-screen scanner in one call, or an embedded camera preview
• Your own reticle, with live focus and torch control
• Decode an image you already have with decodeImage()
