Implement widget to scan QR Codes
Idea
We have to implement simple widget, that we could use to scan QR Codes via web-camera.
Let's name it crnd_web_widget_scan_qrcode
.
We have to apply following logic to this widget:
- Widget should be applicable to Char or Text fields
- Widget have to have button QR-Code displayed right-side of field.
- On clicked we have to try to scan qr-code and save parsed qr-code in the field
- If there was any error, we have to show alert/warning or some other kind of message to user, that scan was not successful.
- Possibly, we could have two varians of widget:
- with original field (value) visible
- without field/value visible (in this canse, we could have only buttons Scan and Clean and some icon that identifies if scan was successful).
