load method

Converts a key into an PictureStreamCompleter, and begins fetching the picture using _loadAsync.

Implementation

@override
PictureStreamCompleter load(AssetBundlePictureKey key,
    {PictureErrorListener? onError}) {
  return OneFramePictureStreamCompleter(
    _loadAsync(key, onError),
    informationCollector: () => <DiagnosticsNode>[
      DiagnosticsProperty<PictureProvider>('Picture provider', this),
      DiagnosticsProperty<AssetBundlePictureKey>('Picture key', key),
    ],
  );
}
