Features

• Supports iOS (arm64), MacOS (arm64/x64), Android (arm64), Windows (x64) (>= 10), Web/WASM
• glTF, KTX, PNG & JPEG texture support
• camera/entity manipulation with mouse (desktop) and gestures (mobile)
• skinning + morph animations

Uses the Filament PBR engine (currently v1.56.4).

Quickstart (Flutter)

From the command line:

flutter channel master
flutter upgrade
flutter config --enable-native-assets  

In your Flutter app:

@override
  Widget build(BuildContext context) {
    return Scaffold(
        body: Stack(children: [
        Positioned.fill(
            child: ViewerWidget(
          assetPath: "assets/cube.glb",
          skyboxPath: "assets/default_env_skybox.ktx",
          iblPath: "assets/default_env_ibl.ktx",
          transformToUnitCube: true,
          initialCameraPosition: Vector3(0, 0, 6),
          background: Colors.blue,
          manipulatorType: ManipulatorType.ORBIT,
          onViewerAvailable: (viewer) async {
            await Future.delayed(const Duration(seconds: 5));
            await viewer.removeSkybox();
          },
          initial: Container(
            color: Colors.red,
          ),
        ))]));
  }

the first time you build an app that consumes this package, the Dart native-assets build system will download static binaries from Cloudflare. This may take a few minutes (depending on which platform you are compiling for). These will be cached, so subsequent builds will be much faster.
