I want to build an mobile app with flutter that gets payment when event is done.
for example, i call a taxi from an app and app is calculates payment from distance, time etc.when finish driving button tapped, app is gonna take payment from saved credit card immediately no 3d secure or anything.
my question is what is that payment method called, how can i implement that service (stripe, paypal etc.)
