🚨 flutter_stripe is in beta - please provide feedback (and/or contribute) if you find issues 💙️

The Stripe Flutter SDK allows you to build delightful payment experiences in your native Android and iOS apps using Flutter. We provide powerful and customizable UI screens and elements that can be used out-of-the-box to collect your users' payment details.

Features #

Simplified Security: We make it simple for you to collect sensitive data such as credit card numbers and remain PCI compliant. This means the sensitive data is sent directly to Stripe instead of passing through your server. For more information, see our Integration Security Guide.

Apple Pay: We provide a seamless integration with Apple Pay.

Payment methods: Accepting more payment methods helps your business expand its global reach and improve checkout conversion.

SCA-Ready: The SDK automatically performs native 3D Secure authentication if needed to comply with Strong Customer Authentication regulation in Europe.

Native UI: We provide native screens and elements to securely collect payment details on Android and iOS.

Pre-built payments UI: Learn how to integrate Payment Sheet, the new pre-built payments UI for mobile apps. This pre-built UI lets you accept cards, Apple Pay, and Google Pay out of the box, and includes support for saving & reusing cards.

Stripe initialization #

To initialize Stripe in your Flutter app, use the Stripe base class.

Stripe offers publishableKey, stripeAccountId, threeDSecureParams and merchantIdentifier. Only publishableKey is required.

Dart API #

The library offers several methods to handle stripe related actions:

Future<PaymentMethod> createPaymentMethod(...);
Future<PaymentIntent> handleCardAction(...);
Future<PaymentIntent> confirmPaymentMethod(...);
Future<void> configure3dSecure(...);
Future<bool> isApplePaySupported();
Future<void> presentApplePay(...);
Future<void> confirmApplePayPayment(...);
Future<SetupIntent> confirmSetupIntent(...);
Future<PaymentIntent> retrievePaymentIntent(...);
Future<String> createTokenForCVCUpdate(...);

Future<void> initPaymentSheet(...);
Future<void> presentPaymentSheet(...);
Future<void> confirmPaymentSheetPayment()

The example app offers examples on how to use these methods.
