3 ways to implement Flutter in-app purchasing

Flutter, developed by Google in 2017, is an open-source UI software development kit used for creating cross-platform applications. For integrating in-app purchases (IAP) into Flutter applications, there are three main plugin options: Flutter's official in_app_purchase, dooboolab's flutter_inapp_purchase, and RevenueCat's purchases_flutter. Each of these plugins offers different functionalities and levels of complexity. In_app_purchase provides extensive control but requires significant code for purchase verification and management. Flutter_inapp_purchase offers more functions but lacks built-in solutions for logic implementations, requiring manual coding for verification. Purchases_flutter simplifies the process by handling purchase validation and other logic through RevenueCat's server, although it is a paid service. Developers must configure in-app purchases on both Android and iOS platforms regardless of the plugin, and each plugin provides methods to query products, handle purchases, and manage subscriptions.
