Implementation

factory RegisterRequestType.fromJson(Map<String, dynamic> json) {

  final pubKeyCredParams = json['pubKeyCredParams'] as List<dynamic>?;

  if (rp is! Map<String, dynamic>) {
    throw FormatException('Expected "rp" to be a Map, got ${rp.runtimeType}');
  }
  if (user is! Map<String, dynamic>) {
    throw FormatException(
      'Expected "user" to be a Map, got ${user.runtimeType}',
    );
  }
