fromJson static method

ListMessagesResponse? fromJson(dynamic value)

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

Implementation

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

    return ListMessagesResponse(
      messages: ChatMessage.listFromJson(json[r'messages']),
      hasMore: mapValueOfType<bool>(json, r'hasMore')!,
      nextCursor: mapValueOfType<String>(json, r'nextCursor'),
