Adding PayTM Payment Gateway to Flutter App | Flutter Tutorial

#flutter #paytm #payments
In this Flutter Video, we will be talking about integrating Paytm Payments Gateway into your Flutter Application. We will be taking a look at getting the credentials from the PayTm Developer Account.

After that we will be initializing the firebase project on our development machine and prepare firebase functions to support paytm payments. Once this is done and we know how the script works, we will modify our flutter application to make the payment requests and get the response from our firebase functions server.

You can download the application code from the link below:
