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 withwarnings
. -
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 withwarnings
.
