function getScaledAssetPath(asset): string {
  var scale = AssetSourceResolver.pickScale(asset.scales, PixelRatio.get());
  var scaleSuffix = scale === 1 ? '' : '@' + scale + 'x';
  var assetDir = assetPathUtils.getBasePath(asset);
  return assetDir + '/' + asset.name + scaleSuffix + '.' + asset.type;
}
Returns a path like 'assets/AwesomeModule/icon@2x.png'
