Setup - Add SHA Keys (Android & Web)

Step 7: Add SHA-1 and SHA-256 Keys

For Android apps to work seamlessly with Firebase (especially for authentication and security), you need to generate and add SHA-1 and SHA-256 keys to the Firebase Console.

Method 1: Using Terminal or Command Prompt

Open a terminal and run the following command:

                keytool -list -v -keystore %USERPROFILE%\.android\debug.keystore -alias androiddebugkey -storepass android
            

Copy the generated SHA-1 and SHA-256 keys and add them to the Firebase Console under:

Project Settings > Your App > SHA Certificate Fingerprints.

Method 2: Using Android Studio

Open your Flutter project in Android Studio.
Go to the bottom panel in Android Studio and select the Terminal tab.

Navigate to the Android Folder

cd android

Run the Gradle Signing Report Command

Run the following command:

./gradlew signingReport

Check the Output

Once executed, you will see an output similar to this:

                Task :app:signingReport
                Variant: debug
                Config: debug
                Store: /Users//.android/debug.keystore
                Alias: AndroidDebugKey
                SHA1: XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX
                SHA256: XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX
            

Why is this Required?

Adding SHA-1 and SHA-256 keys is essential for:

Firebase Authentication using Google Sign-In.
Securing API requests and app integrity validation.
Ensuring proper communication between Firebase and your Android app.
