Fluorite is a new open-source 3D game engine built in Flutter. It allows developers to leverage the Flutter & Dart ecosystem to write game logic, and to integrate it with Flutter’s rich UI toolkit to build stunning interactive experiences across the board.

At the same time, all the complexity is hidden away behind its highly-efficient C++ ECS core, ensuring performance and portability across mobile, desktop, embedded and console platforms.

By integrating Filament, Google’s 3D rendering engine, Fluorite delivers best-in-class PBR rendering performance and quality, enabling high-fidelity creative workflows.

In this intermediate-level session for Flutter and game developers, we will demonstrate Fluorite's tech demos and the code behind them, as well as illustrate how to set up 3D scenes and assets, and leverage Flutter widgets in your game UI. We’ll compare Fluorite’s approach against existing solutions, highlighting how its Dart-first architecture streamlines iteration with Hot Reload, multi-platform support, Widget Inspector, and the full pub.dev ecosystem.
