rename abstract method Null safety

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

Renames this file system entity.

Returns a Future<FileSystemEntity> that completes with a FileSystemEntity instance for the renamed file system entity.

If newPath identifies an existing entity of the same type, that entity is removed first. If newPath identifies an existing entity of a different type, the operation fails and the future completes with an exception.

Implementation

@override
Future<Link> rename(String newPath);
