identical method Null safety
Checks whether two paths refer to the same object in the file system. Returns a Future<bool> that completes with the result.
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.
Completes the returned Future with an error if one of the paths points to an object that does not exist.
@override Future<bool> identical(String path1, String path2) => io.FileSystemEntity.identical(path1, path2);
