Hello Community!
I am trying to integrate Zettle card reader payments into my POS app. Their Android SDK is written in Kotlin, and I'm not sure how to integrate it into my app.
Is such an integration possible with Custom Actions and Custom Functions or do I need to work on this locally using a custom GitHub branch?
Additionally, how can the FlutterFlow app interact with the custom code? Examples: start a payment session when a "Pay button" is tapped or use the output of the payment transaction (As in, a card payment was processed correctly or not) to trigger some flows in the app.
I am pretty new to FlutterFlow so I appreciate any insights you can give. Thanks in advance!
