Custom FlutterFlow Function for RevenueCat Integration -- 2

I'm seeking an experienced Flutter & FlutterFlow developer to create a custom function. This function will enable the integration of RevenueCat purchases with the user ID from Supabase authentication in FlutterFlow. Key Requirements: - The custom function should pass the user ID to the RevenueCat purchase action. - It must handle errors during the purchase process by providing an 'error' output string. - On successful purchases, it should return a 'success' output string. The ideal candidate for this project should have: - Proven experience with Flutter, FlutterFlow, and RevenueCat. - Familiarity with Supabase authentication. - Strong problem-solving skills for creating robust error handling. Please note that the part about the RevenueCat webhook making changes in Supabase is for context only and is not part of the project. Your primary task is to implement the custom code in FlutterFlow.
