Add Firebase email, Google, or social sign-in authentication to a Flutter mobile or web app.
Store and sync real-time app data using Cloud Firestore in a Flutter project.
Send push notifications to Flutter app users via Firebase Cloud Messaging.
Automatically capture and report app crashes in production using the Crashlytics plugin.
Requires a Firebase project with google-services.json on Android and GoogleService-Info.plist on iOS configured before the app runs.
FlutterFire is a collection of official plugins that connect Flutter apps to Firebase services. Flutter is Google's toolkit for building mobile, web, and desktop apps from a single codebase using the Dart programming language. Firebase is Google's platform for app backend services, offering things like user sign-in, real-time databases, file storage, push notifications, and analytics. These plugins are the bridge between the two. Each Firebase service has its own separate plugin in this repository. The stable plugins include authentication for signing users in, Cloud Firestore for a document database, Cloud Storage for files and images, Cloud Messaging for push notifications, Crashlytics for crash reporting, Analytics, and several others. Most plugins support Android, iOS, and web, with macOS support in beta and Windows support varying by plugin. The plugins are distributed as Dart packages on pub.dev, the official package repository for Flutter and Dart. You add them to your app's dependencies like any other Flutter package. Google maintains this repository officially alongside Firebase, making it the standard way to use Firebase in Flutter projects. The README focuses on linking out to documentation and the pub.dev package pages rather than explaining the underlying Firebase services in depth. Setup instructions live in the Firebase documentation, and each plugin links to its own documentation page there. A few sub-projects have been moved to their own separate repositories, including Firebase UI components and the Cloud Firestore ODM, which is a type-safe query layer for Firestore. The project uses a tool called Melos to manage this multi-package repository, since it contains many packages across different Firebase services. All packages are open source. This is the recommended starting point for adding Firebase to any Flutter app.
