identicalSync method Null safety
Synchronously checks whether two paths refer to the same object in the file system.
Comparing a link to its target returns false, as does comparing two links that point to the same target. To check the target of a link, use Link.target explicitly to fetch it. Directory links appearing inside a path are followed, though, to find the file system object.
Throws an error if one of the paths points to an object that does not exist.
