/// @assertion void createSync(
///   String target,
///   {bool recursive = false}
/// )
///  Synchronously create the link. Calling createSync on an existing link will
///  throw an exception.
///
/// If recursive is false, the default, the link is created only if all
/// directories in its path exist. If recursive is true, all non-existing parent
/// paths are created first. The directories in the path of target are not
/// affected, unless they are also in path.
///
/// On the Windows platform, this call will create a true symbolic link instead
/// of a junction. The link represents a file or directory and does not change
/// its type after creation. If [target] exists then the type of the link will
/// match the type [target], otherwise a file symlink is created.
///
/// In order to create a symbolic link on Windows, Dart must be run in
/// Administrator mode or the system must have Developer Mode enabled,
/// otherwise a [FileSystemException] will be raised with
/// `ERROR_PRIVILEGE_NOT_HELD` set as the errno when this call is made.
///
/// On other platforms, the POSIX symlink() call is used to make a symbolic link
/// containing the string target. If target is a relative path, it will be
/// interpreted relative to the directory containing the link.
///
/// @description Checks that this method creates the link. Test [Directory] as a
