The FlutterFire CLI is a useful tool which provides commands to help ease the installation process of FlutterFire across all supported platforms.


The CLI depends on the underlying Firebase CLI. If you haven't done so already, ensure the Firebase CLI is installed on your machine.

Next, install the FlutterFire CLI by running the following command:

dart pub global activate flutterfire_cli

Once installed, the flutterfire command will be globally available.



Some plugins or platforms do not fully support Dart-only Firebase initialization yet, if you need to use the plugins then the manual installation steps should be followed first.

The following table shows the current status of these plugins (plugins not shown in this table are fully supported via Dart-only Firebase initialization):

Dynamic LinksโŒโœ”N/AN/A
Performance Monitoringโœ”โŒโŒN/A

In addition, google_sign_in plugin which is used by firebase_auth also requires manual installation.

Generating Firebase Options#

FlutterFire can now be initialized from Dart on all platforms using Firebase.initializeApp, however the options for different platforms can vary. The CLI can help, by generating a file (by default called firebase_options.dart) which can be used when calling the initialization method.

The CLI extracts information from your Firebase project and selected project applications to generate all the configuration for a specific platform.

In the root of your application, run the configure command:

flutterfire configure

The configuration command will guide you through a number of processes:

  1. Selecting a Firebase project (based on the .firebaserc file or from the Firebase Console).
  2. Prompt what platforms (e.g. Android, iOS, macOS & web) you would like configuration for.
  3. Identify which Firebase applications for the chosen platforms should be used to extract configuration for. By default, the CLI will attempt to automatically match Firebase apps based on your current project configuration.
  4. Generate a firebase_options.dart file in your project.

Once complete, you can now import the generated file and provide it to the initializeApp method:

// Import the generated file
import 'firebase_options.dart';

Then, provide the current platform options via the currentPlatform getter from the DefaultFirebaseOptions class:

await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,



Generates a firebase_options.dart file which can be provided to the options parameter when Initializing Firebase.

flutterfire configure

The command supports the following option arguments:

--project-pSets the Firebase Project ID to use. By default, the CLI will attempt to fetch the project defined in the .firebaserc file, or prompt you to select the project from the Firebase Console.
--account-eSets the email address which should be used to authenticate with Firebase against. By default, this will use the primary account defined on the Firebase CLI.
--out-oSpecifies the path & file name for the generated file. Defaults to "lib/firebase_options.dart".
--ios-bundle-id-iThe bundle identifier of your iOS app, e.g. "". If no identifier is provided then an attempt will be made to automatically detect it from your "ios" folder (if it exists).
--macos-bundle-id-mThe bundle identifier of your macOS app, e.g. "". If no identifier is provided then an attempt will be made to automatically detect it from your "macos" folder (if it exists).
--android-app-id-aThe application id of your Android app, e.g. "". If no identifier is provided then an attempt will be made to automatically detect it from your "android" folder (if it exists).


To view the current version of the CLI, run:
