Static Methods

fromJSON(Map<String, dynamic>? json, {LinkHrefNormalizer normalizeHref = linkHrefNormalizerIdentity}) Link?
Creates an Link from its RWPM JSON representation. It's href and its children's recursively will be normalized using the provided normalizeHref closure. If the link can't be parsed, a warning will be logged with warnings.
fromJSONArray(List? json, {LinkHrefNormalizer normalizeHref = linkHrefNormalizerIdentity}) List<Link>
Creates a list of Link from its RWPM JSON representation. It's href and its children's recursively will be normalized using the provided normalizeHref closure. If a link can't be parsed, a warning will be logged with warnings.
