Cloud Functions Plugin for Flutter

A Flutter plugin to use the Cloud Functions for Firebase API

pub package

For Flutter plugins for other Firebase products, see

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and Pull Requests are most welcome!


To use this plugin:

  1. Using the Firebase Console, add an Android app to your project: Follow the assistant, download the generated google-services.json file and place it inside android/app. Next, modify the android/build.gradle file and the android/app/build.gradle file to add the Google services plugin as described by the Firebase assistant. Ensure that your android/build.gradle file contains the as described here.
  2. Using the Firebase Console, add an iOS app to your project: Follow the assistant, download the generated GoogleService-Info.plist file, open ios/Runner.xcworkspace with Xcode, and within Xcode place the file inside ios/Runner. Don't follow the steps named "Add Firebase SDK" and "Add initialization code" in the Firebase assistant.
  3. Add cloud_functions as a dependency in your pubspec.yaml file.


import 'package:cloud_functions/cloud_functions.dart';

Calling a function:

dynamic resp = await 'YOUR_CALLABLE_FUNCTION_NAME');

Getting Started

See the example directory for a complete sample app using Cloud Functions for Firebase.


  • Set iOS deployment target to 8.0 (minimum supported by both Firebase SDKs and Flutter), fixes compilation errors.
  • Fixes null pointer error when callable function fails with exception (iOS).


  • Bump Android dependencies to latest.


  • Fixed podspec to use static_framework


  • Added missing dependency on meta package.


  • Bump Android and Firebase dependency versions.


  • The Cloud Functions for Firebase client SDKs let you call functions directly from a Firebase app. This plugin exposes this ability to Flutter apps.

    Callable functions are similar to other HTTP functions, with these additional features:

    • With callables, Firebase Authentication and FCM tokens are automatically included in requests.
    • The functions.https.onCall trigger automatically deserializes the request body and validates auth tokens.



Demonstrates how to use the cloud_functions plugin.


This example assumes the existence of the following function:

import * as functions from 'firebase-functions';

export const repeat = functions.https.onCall((data, context) => {
  return {
      repeat_message: data.message,
      repeat_count: data.count + 1,

This function accepts a message and count from the client and responds with the same message and an incremented count.

The description is too short. (-20 points)

Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

Package is pre-v0.1 release. (-10 points)

While there is nothing inherently wrong with versions of 0.0.*, it usually means that the author is still experimenting with the general direction of the API.
