formatFailureText function

String formatFailureText(Object? error, [ StackTrace? stack ])

Renders a readable message plus stack when available.

Accepts String, Failure, Error / Exception and any other thrown object; pass stack when the caller caught one separately. ANSI is stripped and the first line is never duplicated.

Implementation

String formatFailureText(Object? error, [StackTrace? stack]) {
  if (error == null) return stripAnsi((stack?.toString() ?? '')).trim();
  if (error is Failure) {
    return stripAnsi(
      joinMessageStack(error.message, error.stack ?? stack?.toString()),
    ).trim();
  }
  if (error is String) {
    return stripAnsi(joinMessageStack(error, stack?.toString())).trim();
  }
  return stripAnsi(
    joinMessageStack(error.toString(), stack?.toString()),
  ).trim();
}
