Firebase Configuration

Follow the link to create firebase project Firebase:

After completing the project, you will be presented with this type of dashboard.

On the Firebase console, click the Android / IOS icon.

Enter Package Name (e.g., com.example.userApp) and click on register app.

Go to Build -> Authentication tab and click on Get started.

Then select the Email/Password, Google, Apple, and Phone Number one by one and enable them.

Go to Build → Firestore Database tab and click on Get Started.

When you click the Get Started button, a dialogue will appear asking you to choose a mode. Because we are testing, we will select the Start in Test Mode option and then click Next and then enable it.

Follow these steps if you didn't initially provide a SHA certificate fingerprint for your Firebase Android app or if you need to add an additional one:

In your Project settings, go to the Your apps card.

Select the Firebase Android app to which you want to add a SHA fingerprint.

Click Add fingerprint.

Create a file in android folder of your project name key.properties if not exists.

   storePassword=<Your JKS password>
   keyPassword=<Your JKS Key Password>
   keyAlias=<You JKS Key Alias>
   storeFile=<Your jks file location path>

Add following line to your Android/app/build.gradle file above the all android block (Check if this line already exist or not)

   def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists())
   {
          keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   }

Now in app:build.gradle android block check for below lines if not exist Add into your Android/app/build.gradle

   signingConfigs {
      release {
        keyAlias keystoreProperties['keyAlias']
        keyPassword keystoreProperties['keyPassword']
        storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
        storePassword keystoreProperties['storePassword']
      }
   }

   buildTypes {
      release {
        signingConfig signingConfigs.release
      }
   }
