Goal:: What I want is for my marketing team to be able to set up a geofence and a push-message through a custom activity in journey builder.
Problem: The mobilePUSH SDK doesn't support flutter which is what the app team has used to develop our mobile app.
I'm wondering how this would be implemented on a technical level from the SFMC side? What would needed to be sent from the custom activity/SFMC to the app team? Is there any good documentation on implementing this kind of solution?
