We have revamped our Flutter SDK to make it easy for our merchants to integrate and customise their payment flows. Our Flutter SDK supports **Android SDK version 19 and above** and **iOS minimum deployment target of 11 and above** and provides the following.
Pre-built native UI screen to facilitate a quick integration with our payment gateway. This mode handles all the business logic and UI Components to make the payment smooth and easy to use. The SDK allows the merchant to customise the UI in terms of color coding and payment modes shown.
