[MUSIC PLAYING] ALEXANDER NOHE: Hey, everyone. The Firebase Console has a
bunch of different options for adding support to
Android, web, and iOS apps. How can we quickly add Firebase
to all of the supported Flutter platforms? We'll use the Flutterfire CLI. Rather than having to go
to the Firebase Console to get started, you can
call a single command on your development machine
to get up and running fast. Let's hit it up
for use together. To get started,
make sure that you-- one, have a valid
Flutter installation. So I'll just run Flutter
doctor quickly here. Two, have the Firebase
CLI installed, and you have
authenticated to it. Going to run npm i -g firebase
tools to install and then Firebase login to log in. Once that is completed,
call this command-- dart pub global activate
Flutterfire CLI. This command installs
the Flutterfire CLI into our pub cache folder. We need to make sure
that this folder exists in our path environment
variable before we call it. So I'll add that now to
my path and then check that it was added to
my user environment. Great. Now that we have
the CLI installed, let's initialize a new project. I'm creating a new
Flutter project and then opening that
project in our editor. We are in the project directory. I'm opening a terminal and
first adding the Firebase core plugin. This plugin is required
for communicating with your Firebase services. Then we call
Flutterfire configure. This runs through
the configuration wizard for setting up
Firebase with Flutter. It starts by asking you to
choose an existing Firebase project or creating a new one. Since I already have one
created, I will select it here. It then asks you to
select the platforms that you want to target. The current supported platforms
are iOS, Android, macOS, and web. The Flutterfire CLI creates app
descriptors in your selected Firebase project. Or, if there are pre-existing
app descriptors in the project, it links them to
your Flutter project only if they share
a package name. The CLI then creates
a configuration file called Firebase options.dart. That associates your Flutter
app with a corresponding app descriptor for each platform
in the Firebase project. Let's take a look
at that file now. Here we can see some
of my app descriptors. Once that is completed,
in our main app code, we can just call
Firebase initialize app to connect to our
Firebase services, passing in the default Firebase
options, which the Flutterfire CLI created for us. Great. We are all connected. If you want to add an additional
plugin, like Cloud Firestore, you can use the Flutter pub
Git command to add them now. There you go. With just a couple
of minutes used, we have installed,
set up the CLI, and linked our Flutter project
to an existing Firebase project. You are now ready to start
using Firebase in your Flutter project. For the latest information,
please, check out the documentation linked
in the description below. If you found this video

I am so excited to see what you build next. [MUSIC PLAYING]
