FlutterFire
A collection of Firebase plugins for Flutter apps
...It provides modular plugins (e.g. firebase_auth, cloud_firestore, firebase_messaging, etc.) such that apps only include what they need. The central plugin is firebase_core, which initializes the Firebase app instance. Through FlutterFire, developers can use authentication, real-time database, Firestore, cloud functions, analytics, messaging, storage, and more from their Flutter code. The project includes tooling (e.g. the FlutterFire CLI) to assist in configuring Firebase projects and managing plugin versions. The goal is to make Firebase a seamless, first-class backend option for cross-platform Flutter apps, handling platform differences (iOS, Android, web) under the hood.
