@mdazharuddin1011999 it would be nice if you can give credit for original work by referring to the tickets/pull requests in upi_pay repo

[reeteshranjan]

Please look at drenther/upi_pay#17

You mean add some flags like merchant or experimental to control which apps are returned by the getAllUpiApps()?

[reeteshranjan]

Yes. Please see the dartdoc generated docs I have already created for the existing flags getAllUpiApps in my latest commit supports (default behaviour is to give all properly working apps only that are listed in APPS.md).

As of now, I have not tested merchant payments. Working on a project where we are going to setup a merchant account, and then I would test again all the apps for merchant payments. Once that's done, there would be a flag for that as well.

Hi @reeteshranjan and @azhar1038 Does this mean it is suitable for production using verified Apps?

Hi @reeteshranjan and @azhar1038 Does this mean it is suitable for production using verified Apps?

Short answer: no.

Long answer: need more testing. With one person testing, there are lot of blockers. For example, daily transaction limit of either bank or UPI will be reached. So I would suggest developers interested in using upi_pay (this package still to get all the new work I have done) to participate in testing, and push results of what their observations are, so we have enough test data to qualify the package for production.
