Peer-to-Peer Payment Integration With Stream and Flutter

Integrating a peer-to-peer payment solution into a Stream Chat Flutter application enhances user experience by allowing secure and swift financial transactions. This tutorial outlines the steps to set up such a feature using an in-app digital wallet via Rapyd's Wallet API, detailing the creation of a custom Flutter app with necessary dependencies, user authentication, and interface elements like a message input with a payment icon. It explains backend processes such as generating secure API request headers, transferring funds between digital wallets, and confirming transactions. Users initiate payments through a custom widget, and transaction data is displayed with custom attachments in the chat view. The guide also emphasizes safe coding practices like not hardcoding tokens, using sandbox environments for testing, and leveraging Rapyd’s API for financial operations. The successful implementation allows users to send and receive payments efficiently within the chat application.
