Adyen Flutter

The Adyen Flutter package provides you with the building blocks to create a checkout experience for your shoppers, allowing them to pay using the payment method of their choice. This is an overview of the payment methods that you can add to your online payments integration.

You can integrate with the following:

• Drop-in: an out-of-the-box Flutter wrapper for native iOS and Android Drop-in that includes all available payment methods for your shoppers to choose.
• Components: Flutter widgets for native iOS and Android Adyen Components. You use one Component for each payment method. We currently offer the following Components:
  • Card Component: allows shoppers to pay with card. Stored cards are also supported.
  • Google Pay Component: renders a Google Pay button.
  • Apple Pay Component: renders an Apple Pay button.
  • Instant Component: supports payment methods that do not require additional input fields, like PayPal, Klarna and many more.
