These notes visit every concept that appears in the quiz — language & framework, state, navigation, back-end integration, environments, payments, AI agents, responsive design, and more.
When you drag a widget onto the canvas, FlutterFlow generates pure Flutter code in Dart. Flutter compiles that Dart either ahead-of-time (AOT) to ARM binaries for iOS/Android, or to JavaScript for the web.
Because there is no WebView or Java/Swift bridge involved, performance is excellent. You can inspect the generated folders (lib/, flutter_flow/, custom_code/, etc.) after downloading or using Local Run.
