Cloud Functions

What does it do?

Firebase Cloud Functions let you automatically run backend code in response to events triggered by Firebase features and HTTPS requests. Your code is stored in Google's cloud and runs in a managed environment. There's no need to manage and scale your own servers.

Installation

Before installing the Cloud Functions plugin, ensure that you have followed the Getting Started documentation and have initialized FlutterFire.

1. Add dependency

Add the cloud_functions dependency to your projects pubspec.yaml file:

pubspec.yaml
dependencies:
flutter:
sdk: flutter
firebase_core: "^0.5.0"
cloud_functions: "^0.6.0"

2. Download dependency

Download the dependency by running the following command in your project:

$ flutter pub get

3. (Web Only) Add the SDK

If using FlutterFire on the web, add the firebase-functions JavaScript SDK to your index.html file:

web/index.html
<html>
...
<body>
<script src="https://www.gstatic.com/firebasejs/7.20.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/7.20.0/firebase-functions.js"></script>
</body>
</html>

4. Rebuild your app

Once complete, rebuild your Flutter application:

$ flutter run

Next Steps

Once installed, you're ready to start using Cloud Functions in your Flutter Project.

Additional documentation will be available once the Cloud Functions plugin update lands as part of the FlutterFire roadmap.
