AssetLoaderOperations mixin

Mixin that helps load Flutter assets into the model-viewer WebView.

The WebView cannot reach the Flutter asset bundle directly, so these helpers convert asset bytes to base-64 data URIs that model-viewer can use as environment-image or skybox-image values.

Call these methods inside the ModelViewerProViewer.onLoad callback, after the page is fully ready:

ModelViewerProViewer(
  src: 'assets/model.glb',
  controller: _controller,
  onLoad: (meshes) async {
    await _controller.loadSkyboxFromAsset('assets/skybox.hdr');
  },
)
