flutter3d_app

The layer an application is assembled from, as one import.

import 'package:flutter3d_app/flutter3d_app.dart';

final device = await openDevice(width: 1280, height: 720);

Why it is a package

Five packages hold the wiring a game needs beyond the renderer and the simulation: flutter3d_backend (which device to open), flutter3d_session (SceneSurface, RunSession), flutter3d_screens (settings, rebinding, saves), pad_input (a gamepad), pointer_lock (desktop mouse capture). None of the five know about each other, and this package does not change that — it holds no code of its own, only five export lines.

What it buys is that an application's own pubspec.yaml and main.dart say "the assembly layer" once, the way importing flutter3d already says "the renderer" once instead of naming flutter3d_hardware directly.

What is deliberately not behind it

flutter3d, flutter3d_bridge, flutter3d_game, and a genre package. Those are content — what a scene looks like and what kind of game this is — and a facade cannot pick a genre on an application's behalf. See Assembling an application for the full pattern, worked through with apps/flutter3d_demo_dungeon as the example.

Part of flutter3d, an independent implementation of a 3D engine for Flutter — not a fork or a binding of another engine, and not affiliated with the Flutter team. Three switchable rendering backends: Impeller via Flutter GPU, WebGL2, and a software rasteriser. glTF, OBJ and .f3d loading, six lighting models, shadows, bloom, skinning, animation, BVH culling and picking; a deterministic fixed-step game layer with collision, navigation, positional audio, and gamepad and touch input. Three example games — shooter, platformer, racing — each built on its genre package: flutter3d_game_shooter, flutter3d_game_platformer, flutter3d_game_racing. A new game starts from the editor's scaffold, which writes one from a template: flutter3d.pleion.dev/first-project/. Documentation: flutter3d.pleion.dev.
