What it does

Flutterfire Configure is an agent skill from evanca/flutter-ai-rules. Use when adding Firebase to a Flutter project, running flutterfire configure, initializing Firebase in main.dart, or configuring multiple flavors.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps. It works with Firebase and Flutter. The repository describes itself as: Flutter AI Skills and Rules for Claude, Codex, Cursor, and Other AI-Powered IDEs. The licence is MIT.

When your agent uses it

Adding Firebase to a Flutter project
Running flutterfire configure
Initializing Firebase in main.dart
Configuring multiple flavors

Example prompts

“/flutterfire-configure”

Requirements

Node.js

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Verification and Best Practices
Multiple App Flavors

What it can do on your machine

Read from SKILL.md and the folder at commit 7b9cce2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- flutter
- firebase
- npm
- dart
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- firebase.google.com
- firebase.flutter.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutterfire Configure loads about 1.2k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 329 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~42
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FlutterFire Configure Skill

This skill defines how to correctly set up and configure Firebase for Flutter applications.

When to Use

Use this skill when:

Adding Firebase to a Flutter project for the first time.
Running flutterfire configure after adding a new Firebase service or platform.
Initializing Firebase in main.dart.
Setting up separate Firebase projects for multiple app flavors.

1. Prerequisites

Install the required tools:

bash

npm install -g firebase-tools
firebase login
dart pub global activate flutterfire_cli

Minimum platform requirements:

Android: API level 19 (KitKat) or higher
Apple: iOS 11 or higher

2. Setup and Configuration

bash

# From your Flutter project directory:
flutterfire configure

# Add the core Firebase package:
flutter pub add firebase_core

Re-run flutterfire configure any time you add support for a new platform or start using a new Firebase service.
For Android-specific services (Crashlytics, Performance Monitoring), the FlutterFire CLI automatically adds the required Gradle plugins.
Rebuild with flutter run after adding new Firebase plugins.

3. Firebase Initialization

dart

import 'package:firebase_core/firebase_core.dart';
import 'firebase_options.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}

Call WidgetsFlutterBinding.ensureInitialized() before Firebase initialization.
Place Firebase initialization before any other Firebase service calls.
Never modify firebase_options.dart manually — it is auto-generated.
Commit firebase_options.dart to version control — it contains non-secret configuration identifiers.
For Firebase Emulator Suite: await Firebase.initializeApp(demoProjectId: "demo-project-id").

4. Verification and Best Practices

After configuration, verify the setup is working:

Run flutter run and confirm the app launches without Firebase initialization errors.
Check the debug console for Firebase initialized successfully or similar confirmation.
Verify firebase_options.dart was generated with the correct project ID.

Enable Firebase Analytics for optimal experience with Crashlytics, Remote Config, and other products.
Use a consistent Firebase project across all platforms for data consistency.
For iOS/macOS apps using certain Firebase services, add the Keychain Sharing capability in Xcode.
Test the Firebase configuration with both debug and release builds.
Check version compatibility between Flutter plugins and the underlying Firebase SDK.

5. Multiple App Flavors

Create separate Firebase projects per environment (development, staging, production):

bash

flutterfire config \
  --project=flutter-app-dev \
  --out=lib/firebase_options_dev.dart \
  --ios-bundle-id=com.example.flutterApp.dev \
  --ios-out=ios/flavors/dev/GoogleService-Info.plist \
  --android-package-name=com.example.flutter_app.dev \
  --android-out=android/app/src/dev/google-services.json

Centralize Firebase initialization by flavor:

dart

// firebase.dart
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/services.dart';
import 'package:flutter_app/firebase_options_prod.dart' as prod;
import 'package:flutter_app/firebase_options_stg.dart' as stg;
import 'package:flutter_app/firebase_options_dev.dart' as dev;

Future<void> initializeFirebaseApp() async {
  final firebaseOptions = switch (appFlavor) {
    'prod' => prod.DefaultFirebaseOptions.currentPlatform,
    'stg' => stg.DefaultFirebaseOptions.currentPlatform,
    'dev' => dev.DefaultFirebaseOptions.currentPlatform,
    _ => throw UnsupportedError('Invalid flavor: $appFlavor'),
  };
  await Firebase.initializeApp(options: firebaseOptions);
}

dart

// main.dart
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await initializeFirebaseApp();
  runApp(const MainApp());
}

Use appFlavor or environment variables to select the configuration at runtime.
Import each flavor's config with namespace aliases (e.g., as dev).
Use a helper script to automate multi-flavor configuration.
