Car infotainment screen and 3D cluster demo

Gemini 4 Argon + @FlutterDev is cracked. @antigravity built this car infotainment screen and driver cluster with Flutter Scene in a day. It's all one Flutter app. :) The map uses real OpenStreetMap buildings in downtown Boston and a live route from OSRM. The x-ray chassis uses a custom material, and the brake discs glow as the car brakes. The car is a glTF model with working doors, hood, hatch, headlights, and paint options. The parking screen is a mockup of a 360 surround camera view. No embedded engine, no native map SDK, no platform views, just vanilla Flutter with Impeller and built-in SDK features: Flutter GPU. 3D rendered by Flutter Scene, a complete 3D game engine for Flutter. The app is 14,000 lines of Dart, with a center screen, a driver cluster, and a panoramic view of both. No subscriptions, no paid seats, no royalties. Free and open source, forever. Flutter can just do it all.
