href property

Implementation

  // As "{" and "}" are "percent encoded" due to Uri.parse(), we need to
  // revert the encoding first before we can insert the values.
  final decodedHref = Uri.decodeFull(href.toString());

  final expandedHref =
      UriTemplate(decodedHref).expand(userProvidedUriVariables ?? {});
