create abstract method

  1. @override
Future<Link> create(
  1. String target,
  2. {bool recursive = false}

Creates a symbolic link in the file system.

The created link will point to the path at target, whether that path exists or not.

Returns a Future<Link> that completes with the link when it has been created. If the link path already exists, the future will complete with an error.

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. Windows treats links to files and links to directories as different and non-interchangable kinds of links. Each link is either a file-link or a directory-link, and the type is chosen when the link is created, and the link then counts as either a file or directory for most purposes. Different Win32 API calls are used to manipulate each. For example, the DeleteFile function is used to delete links to files, and RemoveDirectory must be used to delete links to directories.

The created Windows symbolic link will match the type of the target, if target exists, otherwise a file-link is created. The type of the created link will not change if target is later replaced by something of a different type, but then the link will not be resolvable by resolveSymbolicLinks.

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.
