You can accept payments in your app using Braintree (a service provided by PayPal) integration. This will also allow your users to pay directly using a credit card or using a service like PayPal, Google Pay, or Apple Pay
Before starting to set up payments, make sure you have:
Sign up for getting access to the Sandboxed environment. You might receive an email with the additional steps for completing the sign-up process. If you already have a Braintree account just Log In.
Navigate to the Braintree Settings page of your FlutterFlow project by going to the Settings and Integrations page (from the Navigation Menu) > Integrations tab > Braintree Payments.
On this page, Enable Payments using the toggle.
Under the Credentials (Sandbox) section, you need to enter the Merchant ID, TokenizationKey, Public Key & Private Key of the Braintree account.
To get the required credentials, navigate to your Braintree account Home page.
Click the gear icon (top-right corner), select Business. From this page, you'll get the Merchant ID.
Now, go to the API page. Here, you'll get the Public Key & Private Key.
To generate a Tokenization Key, go to the API page, and click Generate New Tokenization Key. Copy the Key and enter it in the respective field of FlutterFlow.
Finally, click Deploy to upload the Cloud Functions required for processing a payment using Braintree:
2. Enable Google Pay or Apple Pay (Optional)
Completing the payment integration by following the above steps will allow you to accept payments using a credit card or a PayPal account. Additionally, you can accept payments using Google Pay or Apple Pay.
To accept payments using Google Pay or Apple Pay, you'll need to enter the respective Merchant ID of the Google/Apple account in the Braintree Settings page > Credentials (Sandbox) section.
To know how to find the Google Pay Merchant ID, navigate to this page.

3. Trigger Payment Action
In order to initiate a payment, you have to use the Braintree Payment Action. Know how to define a payment action by going to the following page:
Braintree payments work on real Android devices or in emulators, and App Store purchases only work on real iOS devices. This document has instructions on how to run your app on an Android or iOS device.
The Braintree Payments cannot be tested in Preview Mode, Test Mode, or Run Mode.
