Firebase - VAYESA

To set up Firebase the first thing to do is to have an account.

Register at https://firebase.google.com/ and start creating a new project, it's very easy, just click on the big button that says "Add project".

I have named it FlutterStarterKit but you can name it whatever you want your application to have. It is simple.

Once inside, we must add the platforms we are going to use with their unique package identifier. In this case, we have done it with Android.

Adding Android as a platform to Firebase generates a json file that you must add to the directory: android/app of your application as shown in the image below.

Please note that I deliver the StarterKit with a package name that I have given it. You will have to change it in the following places:

Android:

Change the applicationId in android/app/build.gradle

defaultConfig {
    applicationId "com.flutter.starterkit"
    minSdkVersion flutter.minSdkVersion
    targetSdkVersion flutter.targetSdkVersion
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    multiDexEnabled true
}

iOS:

Change the bundle identifier from your Info.plist file inside your ios/Runner directory.

<key>CFBundleIdentifier</key>
<string>com.flutter.starterkit</string>

Enabling user authentication in Firebase

The next point is to enable user authentication, it is very simple. In the left sidebar we look for the option "Build" and inside "Authentication".

Once inside we must activate the following options:

Activate both methods with the default options.

If we would like to add new authentication methods there is no problem but keep in mind that this starter kit currently only has these two.

Add signatures to test

The next step is to add the security signatures to Firebase to allow us to test. For this we must use the terminal of Visual Studio or Android Studio.

Use the following commands to generate SHA1 and SHA-256 signatures

cd android
./gradlew signingReport

El resultado de este comando será algo como:

 Task :app:signingReport
Variant: debug
Config: debug
Store: C:\Users\Valen\.android\debug.keystore
Alias: AndroidDebugKey
MD5: ED:3C:4C:A3:2E:42:85:A8:33:D8:32:FB:34:F5:A8:CA
SHA1: EE:AC:F0:B0:29:52:BE:CA:2C:D3:95:0F:5C:8E:11:C3:60:7A:45:35
SHA-256: 70:C8:13:F1:85:A2:6F:8C:D8:6D:60:E0:1C:3B:10:13:0E:A3:DD:43:4B:E9:75:62:28:6C:DB:CA:F1:C8:DF:A8
Valid until: domingo, 2 de febrero de 2053

Now we must go to the configuration of our application in Firebase and add them as fingerprints

For now, this is all the configuration we need to do in Firebase to start testing our application.
