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. :)
