The example app lives in flutter_app/ and is a member of the workspace, so its dependencies are resolved automatically with the rest of the repo.
From the repo root:
flutter pub get # resolves the workspace
cd examples/flutter_app
flutter create . --platforms=macos # gitignored platform stubs
flutter run --enable-flutter-gpu --enable-impellerThe build hook (hook/build.dart) compiles the engine's shaders, cooks the loose textures, compiles the .fmat materials, and converts the glTF assets in assets_src/ into .fsceneb scene packages, all into flutter_scene_generated/.
