Implementation

@override
  String toString() {
    List<String> auth_params = <String>[];

    if (_response == null) {
      throw AssertionError(
          'response field does not exist, cannot generate Authorization header');
    }

    auth_params.add('algorithm=$_algorithm');
    auth_params.add('username="${_credentials.username}"');
    auth_params.add('realm="$_realm"');
    auth_params.add('nonce="$_nonce"');
    auth_params.add('uri="$_uri"');
    auth_params.add('response="$_response"');
    if (_opaque != null) {
      auth_params.add('opaque="$_opaque"');
    }
    if (_qop != null) {
      auth_params.add('qop=$_qop');
      auth_params.add('cnonce="$_cnonce"');
      auth_params.add('nc=$_ncHex');
    }
    if (_stale != null) {
      auth_params.add('stale=${_stale! ? 'true' : 'false'}');
    }
    return 'Digest ${auth_params.join(', ')}';
  }
