QRCode: Zoom Option

[JasonIsAzn]

Overview

It is possible for events to have two QRCodes being shown on the event slides (A QRCode for the sign in, An external QRCode for an interest form). The QRCode scanner needs a zoom so that a user can zoom into one QRCode anywhere in the room.

Task

• Add zoom option to camera

Addtional

See QRCodeScanningScreen.tsx to see the current implementation

The problem with two qrcdoe side-by-side is now fixed. The QRCodeScanner will ignore all other QRCodes. However zoom feature will still be needed for scanning the qrcode from a distance.
