rename method

  1. @override
Future<T> rename (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 replaced. If newPath identifies an existing entity of a different type, the operation fails and the future completes with an exception.

Implementation 

@override
Future<T> rename(String newPath) async =>
    wrap(await delegate.rename(newPath) as D);
