How to change the payee when making a purchase

[AdivonSlav]

Hello, I'm currently trying to implement flutter_braintree in a Flutter app i'm doing as a university project. For my specific needs, I need to be able to support payments between users. In the Braintree and PayPal docs, simply setting the payee makes this possible. Is there any way in flutter_braintree to do this, or if not what would be needed to add his functionality to flutter_braintree? Thank you!
