| /// {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 if a link with the target another link pointing to |
| /// a file was created and then this link was deleted and a directory with the |
| /// same name created, then on Windows the link became invalid on other |
| /// platforms it changes its type |
