FlutterFlow is an online platform designed to simplify the process of building mobile applications. It allows users to create visually appealing and powerful apps using a drag-and-drop interface, without requiring extensive coding knowledge. Built on top of the Flutter framework, FlutterFlow enables developers and designers to collaboratively design, prototype, and develop production-ready apps. The platform offers features like Firebase integration, custom functions, API support, and pre-built widgets to streamline app development. Users can export their projects as Flutter code, bridging the gap between visual design and actual production code, which facilitates a smooth transition from design to deployment.
