build_hooks library

Build-hook helpers for flutter_scene.

Call these from your app's hook/build.dart at build time. buildScenes converts glTF (.glb) and authored .fscene sources into flutter_scene's .fsceneb package format, buildMaterials compiles .fmat custom-material files into a Flutter GPU shader bundle plus a parameter sidecar, buildTextures cooks loose images into the engine's compressed .fstex container (or standard ETC1S .ktx2, see TextureEncoding), and buildTargetShaderBundleJson compiles raw shader manifests without unused platform backends. buildEngineAssets is optional, putting the shaders flutter_scene itself needs in this app's generated assets rather than in flutter_scene's own.

Everything lands in the app's flutter_scene_generated/ directory and is loaded by source path through loadScene/loadFmatMaterial/loadTexture. dart run flutter_scene:init writes this hook and the one pubspec entry the directory needs.
