# rename method Null safety

Future<FileSystemEntity> rename (

1. String newPath

)

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

    Future<FileSystemEntity> rename(String newPath);
