/**
 * @assertion Future<bool> exists()
 * Checks whether the file system entity with this path exists. Returns a
 * Future<bool> that completes with the result.
 *
 * Since FileSystemEntity is abstract, every FileSystemEntity object is actually
 * an instance of one of the subclasses File, Directory, and Link. Calling
 * exists on an instance of one of these subclasses checks whether the object
 * exists in the file system object exists and is of the correct type (file,
 * directory, or link). To check whether a path points to an object on the file
 * system, regardless of the object's type, use the type static method.
 * @description Checks that this method checks whether the file system entity
 * with this path exists and has correct type. Test Link
