Hi,
I am expert in Android [ kotlin ], [ java ], [ Flutter ] apps working with quite a few years,
I have read your project proposal and check the link.
I can add extra feature in your Android [ Java ] OMR scanner app in accordance with your needs.
It seems we need to discuss in detail about requirements. Do you download it from Github? Can you share the link of Github where from you download the app.
So, it's would be extendable latter if you want to add new functionality in your app.
I will provide you a quality work.
Let's chat to proceed.
