Implementation

Map<String, dynamic> getValidHeaders(Map<String, dynamic>? headers) {
  final result = <String, dynamic>{};

  if (headers == null || headers.isEmpty) {
    return result;
  }

  headers.forEach((key, value) {
    if (allowedHeaders.containsKey(key)) {
      result[key] = value;
    }
  });

  return result;
}
