## Implementation

    bool getContainsBiometrics() {
      Pointer<Bool> pContainsBiometrics = calloc();
      try {
        var err = biosealSDK.id3BiosealField_GetContainsBiometrics(_pHandle.value, pContainsBiometrics);
        if (err != BiosealError.success.value) {
          throw BiosealException(err);
        }
        final vContainsBiometrics = pContainsBiometrics.value;
        return vContainsBiometrics;
      } finally {
        calloc.free(pContainsBiometrics);
      }
    }
