fromJSON static method

Link? fromJSON(Map<String, dynamic>? json, {LinkHrefNormalizer normalizeHref = linkHrefNormalizerIdentity})

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.

Implementation

static Link? fromJSON(Map<String, dynamic>? json,
    {LinkHrefNormalizer normalizeHref = linkHrefNormalizerIdentity}) {
  String? href = json?.optNullableString("href");
  if (href == null) {
    Fimber.i("[href] is required: $json");
    return null;
  }

  return Link(
      href: normalizeHref(href),
      type: json.optNullableString("type"),
      templated: json.optBoolean("templated", fallback: false),
      title: json.optNullableString("title"),
      rels: json.optStringsFromArrayOrSingle("rel").toSet(),
      properties: Properties.fromJSON(json.optJSONObject("properties")),
      height: json.optPositiveInt("height"),
      width: json.optPositiveInt("width"),
      bitrate: json.optPositiveDouble("bitrate"),
      duration: json.optPositiveDouble("duration"),
      languages: json.optStringsFromArrayOrSingle("language"),
      alternates: fromJSONArray(json.optJSONArray("alternate"),
          normalizeHref: normalizeHref),
      children: fromJSONArray(json.optJSONArray("children"),
          normalizeHref: normalizeHref));
