 # Getting started
 
 ```shell
-$ flutter pub add local_file_preferences
+$ flutter pub add padding_extra
 ```
 This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):
 
 ```yaml
 dependencies: 
-local_file_preferences: {*version}
+padding_extra: {*version}
 ```
 Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.
