fromJson static method

OriginatorImage? fromJson(
  1. dynamic value
)

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

Implementation

// ignore: prefer_constructors_over_static_methods
static OriginatorImage? 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'sizeKey'),
          'Required key "OriginatorImage[sizeKey]" is missing from JSON.');
      assert(json[r'sizeKey'] != null,
          'Required key "OriginatorImage[sizeKey]" has a null value in JSON.');
      assert(json.containsKey(r'url'),
          'Required key "OriginatorImage[url]" is missing from JSON.');
      assert(json[r'url'] != null,
          'Required key "OriginatorImage[url]" has a null value in JSON.');
      return true;
    }());

      sizeKey: mapValueOfType<String>(json, r'sizeKey')!,
      url: mapValueOfType<String>(json, r'url')!,
