flutter3d_samples #

The models flutter3d is tested against and its demo browses. Test data, not a library: the whole of the Dart here is two path constants.

import 'package:flutter3d_samples/flutter3d_samples.dart';

// In a widget, through a bundle:
final bytes = await rootBundle.load('$kSamplesAsset/BoxTextured.glb');

// In a test, from disk:
final bytes = File('$kSamplesPath/BoxTextured.glb').readAsBytesSync();

What is in it #

Why it is its own package #

These files were declared in flutter3d's own flutter.assets, so every application that depended on the engine bundled 4.1 MB of test models it never loads, and the engine's published archive was mostly somebody else's data. They are still needed — by the decoder tests, which read every path above, and by the demo, which browses them — so they moved rather than went. A game depends on the engine and gets no fixtures; a test or a demo depends on this.

Licence #

The package is MIT, like the rest of this repository. The models are not ours and keep their own terms, recorded per file with author and source in assets/ATTRIBUTION.md. Everything shipped here is CC0 or public domain.

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: https://flutter3d.pleion.dev/first-project/. Documentation: https://flutter3d.pleion.dev.
