I want to create my own QR Scanner which automatically detects or fetches UPI info, particularly UPI ID from any QR if present. The mobile_scanner package in flutter gets the code from any QR but from the long string i can't fetch just the UPI.

eg: From a complex QR it reads.

I want to automatically fetch "shradhatravel.62029515@hdfcbank" like in Paytm and other apps.

You may want to use the issue reporting page to ask the owner of the package: https://github.com/juliansteenbakker/mobile_scanner/issues – Dong Chen Jun 07 '22 at 23:30
Have you tried parsing the string? any QR reader will return the string value of the QR code and you need to parse it to get the values you want. – Carlos Sandoval Jun 08 '22 at 05:38
