rename abstract method Null safety

Future<Link> rename(
  1. String newPath
)
override

Renames this link.

Returns a Future<Link> that completes with a Link for the renamed link.

If newPath identifies an existing link, that link is removed first. If newPath identifies an existing file or directory, the operation fails and the future completes with an exception.

Implementation

Future<Link> rename(String newPath);
