Using packages

Your Celest backend is a pure Dart application. Any Dart packages which can be used in a Dart app can be used in your functions. For example, to communicate with systems outside of Celest, you could use package:http, package:dio, or any other HTTP client compatible with pure Dart.

Adding a Dart package to your backend

To add a package for use in your backend, navigate in your terminal to the <flutter_app>/celest folder and then run the dart pub add <package-name> command.

$ dart pub add <package-name>
