FlutterFlow recently introduced Libraries, a feature enabling the creation of reusable resources and custom integrations, prompting Adapty to develop an integration that combines their in-app subscription management platform with FlutterFlow's capabilities. By leveraging their existing Flutter SDK, Adapty's FlutterFlow Library facilitates in-app purchase management, paywall creation, and A/B testing without requiring app updates. The library offers a set of custom actions and data types to integrate seamlessly within FlutterFlow, allowing developers to experiment with paywalls and optimize user engagement effectively. Adapty's integration process involved adding dependencies, initializing the SDK, and creating custom data types and actions, which are now accessible through the FlutterFlow Marketplace, expanding Adapty's reach and offering new monetization opportunities. The initiative underscores the benefits of developing FlutterFlow integrations, such as reaching a broader audience and simplifying access to product features, encouraging other developers to explore similar possibilities.
