Overview
RFW (Remote Flutter Widgets) is a library that enables runtime rendering of declarative widget descriptions, allowing UIs to be defined and updated remotely. It supports server-driven UI patterns by fetching widget configurations from a remote source and dynamically building Flutter widgets at runtime. This facilitates flexible, dynamic interfaces without requiring app updates. RFW integrates seamlessly with Flutter’s declarative framework and works across all major platforms including Android, iOS, Web, macOS, Windows, and Linux.
Use cases
