Implementation

@override
CubeLinkTarget linkTarget(String path) {
  try {
    final type = FileSystemEntity.typeSync(path, followLinks: false);
    if (type != FileSystemEntityType.link) {
      return (isLink: false, target: null);
    }
    return (isLink: true, target: Link(path).targetSync());
  } on Object {
    // Link node we could stat but cannot read: fail closed rather than
    // guess.
    return (isLink: true, target: null);
  }
