Chapter 10: Backend as a Service (BaaS), Firebase, FlutterFire

In this chapter, we'll get familiar with the term BaaS, the services of Firebase, and Firebase's libraries that we can use to integrate some of those services into our Flutter apps. We'll then see some of the Firebase services in action in a real-time updating forum application.

What's BaaS?

Backend-as-a-Service (BaaS) is a cloud service model where all of an apps' back-end services are outsourced to a service provider. BaaS providers deliver and maintain all APIs and libraries needed to use their services.

What's Firebase?

Firebase is Google's BaaS platform. It provides many pre-built services, including:

  • Authentication
  • File storage (Storage)
  • Database (Firestore, Realtime Database)
    • NoSQL, collection and document based database
  • Crash reporting (Crashlytics)
  • Analytics
  • etc.

Getting started with Firebase

To use Firebase services, all we need to have is a Google account. If we visit https://firebase.google.com in a browser after signing in with a Google account, we can access our Firebase console right away.

No FlutterFire love for Windows and Linux yet, so the desktop support is for macOS only at the writing of this material.

Show around the Firebase Console.

Create a new app.

Show menu.

Enable:

  • Authentication
  • Firestore
  • Storage
  • Crashlytics
  • Analytics

FlutterFire

(Rt Database has no Web support, but use Firestore instead!) Crashlytics has no Web support :(

Authentication

We have to enable it on the console. For the sake of simplicity, we'll use the email/password login method.

Firestore

https://firebase.flutter.dev/docs/firestore/usage/

dispose - we're using StreamBuilders, so there's no need to manually dispose the subscriptions

Storage

File storage, the folder structure is flexible.

Easy to upload and download/reference files.

Crashlytics

Crash reporting.

Analytics
