FlutterFlow generates production-ready Flutter (Dart) code under the hood, meaning developers can export clean, maintainable code at any time with no vendor lock-in. The platform supports custom widgets and custom actions written in Dart, enabling developers to extend the visual builder with arbitrary code when needed. It integrates natively with Firebase (Firestore, Auth, Storage) and Supabase for backend/database needs, and supports any RESTful API or third-party service. Team workflows are supported via branching and collaborative editing, making it suitable for multi-developer projects at scale.
