fromJson static method

FeedPostMediaItem? fromJson(dynamic value)

Returns a new FeedPostMediaItem instance and imports its values from value if it's a Map, null otherwise.

Implementation

// ignore: prefer_constructors_over_static_methods
static FeedPostMediaItem? fromJson(dynamic value) {
  if (value is Map) {
    final json = value.cast<String, dynamic>();

    // Ensure that the map contains the required keys.
    // Note 1: the values aren't checked for validity beyond being non-null.
    // Note 2: this code is stripped in release mode!
    assert(() {
      assert(json.containsKey(r'sizes'), 'Required key "FeedPostMediaItem[sizes]" is missing from JSON.');
      assert(json[r'sizes'] != null, 'Required key "FeedPostMediaItem[sizes]" has a null value in JSON.');
      return true;
    }());

    return FeedPostMediaItem(
      title: mapValueOfType<String>(json, r'title'),
      linkUrl: mapValueOfType<String>(json, r'linkUrl'),
      sizes: FeedPostMediaItemAsset.listFromJson(json[r'sizes']),
    );
  }
  return null;
