You can update Flutter UI dynamically by using server-side rendering with the rfw package to fetch text-based widget definitions over HTTP. This allows your server to push real-time content and layout changes to active apps without requiring a new download.

Server-driven UI in Flutter using RFW is a technique where your server defines and serves text-based widget definitions that the client app parses and renders. This mechanism enables immediate remote updates to your app's interface and data exchange via HTTP.

Yes, you can build a server-first Flutter app by using Dart Frog to serve RFW widget definitions over HTTP. This setup supports flexible UI management and real-time content delivery by having your backend control the rendering logic.

To push real-time content updates to a Flutter app, modify the RFW text definitions stored on your server. The app fetches these updated definitions via HTTP to instantly render new promotional banners, product displays, or layouts without a new release.

The rfw package supports A/B testing layouts by allowing your server to dynamically push different UI definitions to specific users. You can update server-side RFW text files to instantly change feature layouts for targeted campaigns without an app update.

Server-driven UI in Flutter requires an active HTTP connection to fetch updated RFW definitions and relies on text-based formats that cannot execute arbitrary Dart logic. You must manage state synchronization and offline fallbacks manually within the client application.
