Not a Flutter developer myself (i use Kotlin), but one reason could be that you have integrated the camera directly into your app for which you might have imported a library, sometimes these libraries create different builds for different Android architectures, so when you compile a universal apk, it includes the builds for all architectures, hence could be the reason for large size, if you directly use androids camera from intent, that might reduce the size, anyways if the library is the reason for the size, it won't matter when the user will download the app from playstore, its size should be reduced as per their device's architecture, I would have loved to help in the development, if it was in kotlin. can I have your permission to use this idea to make a kotlin version?

In case it helps you in any way, you might want to look at how Jupiter CSB EDGE Credit Card has implemented this feature on similar lines.

To give you a gist about its rewards design, this card offers FLAT 2% on a chosen category (Shopping, Dining or Travel) and 0.4% on other categories.

So, the QR scanner in their app scans and lets you know beforehand whether or not you would be eligible to earn 2% or 0.4% which in turn helps you to make an informed decision.

I believe they determine the MCC from the QR itself to identify if it falls under Shopping, Dining or Travel categories.

Wow. This must be implemented in all the UPI apps, to make the user well informed.
