Sample applications

Quick start flutter app: You can learn how the In-App-Payments Flutter plugin is used by getting started with the example app, a quick-start Flutter app that lets you take a payment after completing 6 set up steps.
Quick start backend app: The In-App Payments Server Quickstart takes the nonce created by the flutter app and uses it to create a payment credited to your Square account. Use this backend sample to quickly create a complete payment flow.
