framesOf static method

List<String> framesOf(StackTrace? stack)

The frames of stack that are not the framework's, as frames holds them.

Read off the text, in both of the shapes a stack arrives in: the VM's own, #3 member (uri:12:5), and the terse one package:stack_trace prints, uri 12:5 member, whose file paths are relative to the working directory and are resolved against it here.

Implementation

static List<String> framesOf(StackTrace? stack) {
  if (stack == null) return const [];
  var frames = <String>[];
  for (var line in '$stack'.split('\n')) {
    line = line.trimRight();
    var match = _vmFrame.firstMatch(line) ?? _terseFrame.firstMatch(line);
    if (match == null) continue;
    var written = match.group(1)!;
    var uri = _scheme.hasMatch(written)
        ? written
        : '${Uri.base.resolveUri(Uri.file(written))}';
    if (_framework.any(uri.startsWith)) continue;
    var column = match.group(3);
    frames.add(
      column == null
          ? '$uri:${match.group(2)}'
          : '$uri:${match.group(2)}:$column',
    );
    if (frames.length == maxFrames) break;
  }
  return frames;
