Configure Firebase

Go to the firebase project you might created while following backend documentation.
If you don't have, follow the steps below and create one project.
At first, follow this link https://firebase.google.com/

Now, we first have to create a Firebase project. Firebase project will go through and describe what it is. This allows us to add an app to that project. It can have many projects inside of Firebase.

Now, we have to give a name and id to the project, enable Google Analytics for the project, set an analytics location, and accept all the terms and conditions. Firebase console automatically creates a unique id for the project.

Step 1 : Giving a name to the project

Step 2 : Enable Google analytics for the project

Step 3 : First Choose default Firebase account and then create project

Add Android app to Firebase

In the next step, we have to choose the platform to add Firebase to our application. The platform can be Android, iOS, Web etc..

Your package name is generally the applicationId in your build.gradle (app-level) file
See this page for information on using keytool to get the SHA-1 hash of your signing certificate
Add your applicationid in the first field and SHA-1 to the third field as shown in the image below.

Download the google-services.json file & place it in your project's app root directory.

Back in the Firebase console-setup workflow, click Next to skip the remaining steps and then finish and complete

Add iOS app in Firebase

We have to choose the platform to add Firebase to our application. Click on iOS.

On the next screen, enter your iOS bundle ID & App nickname and click on Register App. You can find your bundle ID in the General tab for your app's primary target in Xcode. If specified, the app nickname will be used throughout the Firebase console to represent this app. Nicknames aren't visible to users.

Download the GoogleService-Info.plist file & move the GoogleService-Info.plist file you just downloaded into the root of your Xcode project and add it to all targets. Make sure the config file is not appended with additional characters, like (2).

Back in the Firebase console-setup workflow, click Next to skip the remaining steps and the finish.
