Authentication and Authorization of flutterflow app using AWS cognito

I have got app built using flutterflow.io.
I need to connect with backend.
Here I have to use AWS congnito for authentication and authorization.

You will do this project in 2 ways.
1. Implement AWS cognito functionality in Flutterflow
2. Implement AWS cognito functionality to flutter code downloaded from Flutterflow.


So I am looking for flutterflow(flutter) and AWS cognito expert.
