formatStackTrace method Null safety

Chain formatStackTrace(
  1. StackTrace stackTrace,
  2. {bool? verbose}
)

Converts stackTrace to a Chain and formats it according to the user's preferences.

If verbose is true, this doesn't fold out irrelevant stack frames. It defaults to the current test's Metadata.verboseTrace configuration, or false if there is no current test.

Implementation

Chain formatStackTrace(StackTrace stackTrace, {bool? verbose}) {
  verbose ??= Invoker.current?.liveTest.test.metadata.verboseTrace ?? false;

  var chain =
      Chain.forTrace(_mapper?.mapStackTrace(stackTrace) ?? stackTrace);
  if (verbose) return chain;

  return chain.foldFrames((frame) {
    if (_only.isNotEmpty) return !_only.contains(frame.package);
    return _except.contains(frame.package);
  }, terse: true);
}
