Step 2: Add Fingerprints for Android (Optional for Android apps)

If you're configuring Firebase for Android, you need to add the correct fingerprints for your app:

1. Open a terminal and run the following command to get your debug keystore fingerprint:

   keytool -list -v -keystore C:\Users\<your-username>\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

2. Go to Project Settings in the Firebase Console.

3. Add the fingerprints you obtained from the command above.

If you're working on a web app, you need to configure the Firebase settings in your web project:

2. In Project Settings, under the General tab, find your Firebase web configuration.
3. Follow the instructions to add the configuration to your /web/index.html file.

Step 4: Run Flutterfire Configure

Once you’ve completed the setup in the Firebase Console, run the following command in your terminal to update your Flutter project with the latest Firebase configurations:

flutterfire configure

This will refresh your Flutter project to ensure the changes you made on the Firebase Console are reflected in your app.
