dio_logger error at web environment.

[wangmir]

dio_logger emit error on XMLHttpRequest error of web environment when using flutter_loggy_dio.

XMLHttpRequest error is derived from CORS issue when launching flutter web environment (especially when debugging).

And in this situation, if I use dio logging with flutter_loggy_dio, the error log is not printed properly and even for the exception path because it crashed at logging stage rather than network error.

at dio_logger.dart,

_value was "<<< DioError │ GET │ null null │ null"

crash point in logger was on flutter_loggy_dio/diop_logger.dart: 166

  void _commit(LogLevel level) {
    if (level.priority >= LogLevel.error.priority) {
      final String _valueError = _value.toString();
      final String _errorTitle = _valueError.substring(0, _valueError.indexOf('\n')); // this line
      final String _errorBody = _valueError.substring(_errorTitle.length);
      loggy.log(level, _errorTitle, _errorBody);
    } else {
      loggy.log(level, _value.toString());
    }
    _value.clear();
  }

and error was
