# rename method Null safety

Future<File> rename (

1. String newPath

)
override

Renames this file. Returns a `Future<File>` that completes with a File instance for the renamed file.

If `newPath` identifies an existing file, that file is replaced. If `newPath` identifies an existing directory, the operation fails and the future completes with an exception.

## Implementation

    Future<File> rename(String newPath);
