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.

Flutter is a 3D engine now. 99 seconds from my Flutter & Friends talk. Everything in the cut is rendered by Flutter on the stable channel, on Impeller and Flutter GPU. No platform views, no native textures piped in from another engine, no custom fork. The engine is Flutter Scene, a complete 3D game engine for Flutter. Complete means graphics, physics, audio, networking, an editor, and tools for AI coding agents, in one open source project. It runs on macOS, Linux, Windows, iOS, Android, web, and custom embedders. It scales down to a single model in a widget and up to full games, and dozens of contributors have landed work in it this year. A scene is a widget. Put it in a Column, stack UI over it, or draw it transparent over the UI so physics objects cast shadows on your buttons. And hot reload works on the scene itself. Change a light or a material in Dart and it updates in place. The full talk covers materials, lighting, the editor, and agent skills. Link in the reply. :)

Dice rolling across a Flutter widget tree. The cards, the button, and the score are plain widgets, and the dice cast shadows on them. :) The dice are physics bodies drawn by Flutter Scene, a complete 3D game engine for Flutter, in a transparent layer on top. An invisible shadow catcher material stands in for the screen surface, so the only thing the 3D layer draws is the dice and the shadows they leave on the UI. Land a die hard enough on a card and it cracks. The shards are the card's own pixels, thrown as physics bodies, and they cast shadows like everything else. No image assets anywhere. The stripes, the cards, the pip faces, and the wood and marble textures are painted or baked at startup. Physics is Rapier through flutter_scene_rapier, and this was recorded in debug mode. The shadow catcher material shipped today in flutter_scene 0.23. This version of the dice example, with the count-up, the glass, and the breaking cards, lands in the example app with the next release.
