dart:io

rename abstract method

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

Future<FileSystemEntity> rename(String newPath);
