fromJson static method

VideoReactionResponse? fromJson(dynamic value)

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

Implementation

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

    return VideoReactionResponse(
      custom: mapCastOfType<String, Object>(json, r'custom') ?? const {},
      emojiCode: mapValueOfType<String>(json, r'emoji_code'),
      type: mapValueOfType<String>(json, r'type')!,
