error method

void error(String message, { Exception? exception, String? hint, bool newParagraph = false, StackTrace? stackTrace, bool forcePrintStackTrace = false, })

Error Messages Guidelines

Tone: Polite and encouraging, never accusatory. Format:

ERROR: <Short description>
<Actionable suggestion/hint>

Example:

ERROR: Could not update the environment variable.
The variable does not exist, double check the name by running the list command:
 $ scloud env list

Implementation

void error(
  final String message, {
  final Exception? exception,
  final String? hint,
  final bool newParagraph = false,
  final StackTrace? stackTrace,
  final bool forcePrintStackTrace = false,
}) {
  final String msg;
  if (exception != null) {
    final separator = isPunctuation(message[message.length - 1]) ? ' ' : ': ';
    final eMessage = userFriendlyExceptionMessage(exception);
    final suffix = isPunctuation(eMessage[eMessage.length - 1]) ? '' : '.';
    msg = '$message$separator$eMessage$suffix';
  } else {
    msg = message;
  }

  _logger.error(
    msg,
    newParagraph: newParagraph,
    stackTrace: configuration?.verbose == true || forcePrintStackTrace
        ? stackTrace
        : null,
  );

  if (hint != null) {
    _logger.info(
      hint,
      type: cli.TextLogType.hint,
    );
  }
}
