Plugin.Firebase.Auth.Google 3.1.0

Auth

You can use Firebase Authentication to allow users to sign in to your app using one or more sign-in methods, including email address and password sign-in, and federated identity providers such as Google Sign-in and Facebook Login.

Installation

Nuget

Install-Package Plugin.Firebase.Auth

Setup

• Follow the instructions for the basic setup
• Enable Authentication at your project in the Firebase Console.
• When using Plugin.Firebase.Auth.Google, add the following lines of code after calling CrossFirebase.Initialize():

#if IOS
  FirebaseAuthGoogleImplementation.Initialize();
#elif ANDROID
  FirebaseAuthGoogleImplementation.Initialize("your-google-request-id-token");
#endif

• The googleRequestIdToken can be accessed at the Google API Console (make sure to use the Client-ID of the Web client)

iOS specifics

• Enable keychain entitlement in Entitlements.plist:

  <dict>
    <key>keychain-access-groups</key>
    <array>
      <string>$(AppIdentifierPrefix)my.fancy.app</string>
    </array>
  </dict>

• In case you are using Authentication via Google, add an url scheme to your apps Info.plist:

  <key>CFBundleURLTypes</key>
  <array>
    <dict>
      <key>CFBundleURLSchemes</key>
      <array>
        <string>com.googleusercontent.apps.123456-abcdef</string>
      </array>
    </dict>
  </array>

• For more specific instructions take a look at the official Firebase documentation

Android specifics

• Make sure you have added the SHA-1 fingerprint matching the keystore you've used for signing the app bundle to the android project settings in the firebase console:

• Call FirebaseAuthImplementation.HandleActivityResultAsync(requestCode, resultCode, data); from MainActivity.OnActivityResult(...)
• If you are on version 2.0.5 or later, add the following package to your project's .csproj file to prevent build errors:

  <PackageReference Include="Xamarin.AndroidX.Browser" Version="1.6.0.2" />

For more specific instructions take a look at the official Firebase documentation

Usage

Take a look at the documentation for the AdamE.Firebase.iOS.Auth packages, because Plugin.Firebase's code is abstracted but still very similar.

Since code should be documenting itself you can also take a look at the following classes:

• src/.../IFirebaseAuth.cs
• src/.../IFirebaseUser.cs
• tests/.../AuthFixture.cs
• sample/.../AuthService.cs
