loadBaseShaderLibrary function

Future<void> loadBaseShaderLibrary()

Asynchronously loads and caches the base shader bundle. Idempotent. Called by Scene.initializeStaticResources so the synchronous baseShaderLibrary getter has a cached library to return (required on web, where shader assets can't be read synchronously).

Implementation

Future<void> loadBaseShaderLibrary() async {
  if (_baseShaderLibrary != null) {
    return;
  }
  final lib = await gpu.loadShaderLibraryAsync(_kBaseShaderBundlePath);
  if (lib == null) {
    throw Exception(
      "Failed to load base shader bundle! ($_kBaseShaderBundlePath)",
    );
  }
  _baseShaderLibrary = lib;
}
