gigya_flutter_plugin 0.2.0

SAP Gigya Flutter plugin

Flutter plug-in for SAP Customer Data Cloud

A Flutter plugin for interfacing Gigya's native SDKs into a Flutter application using Dart.

Description

Flutter plugin that provides an interface for the Gigya API.

Developers Preview Status

The plugin allows you to use the core elements & business API flows available within the SAP Customer Data Cloud mobile SDKs. This plugin is currently in an early developers preview stage.

Requirements

Android SDK support requires SDK 14 and above.

Download and Installation

Add the plugin in your pubspec.yaml fie.

Setup & Gigya core integration

Android setup

Important: Make sure you have configured the basic steps needed for integrating the Android SDK

If you need custom scheme(Optional):

class MyApplication : FlutterApplication() {

    override fun onCreate() {
        super.onCreate()
        GigyaFlutterPlugin.init(this, GigyaAccount::class.java)
    }
}

iOS setup

Navigate to <your project root>/ios/Runner/AppDelegate.swift and add the following:

import gigya_flutter_plugin
import Gigya

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {

    // Copy this code to you Android app.
    //
    GeneratedPluginRegistrant.register(with: self)
    SwiftGigyaFlutterPlugin.register(accountSchema: UserHost.self)

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Important: Make sure you have configured your info.plist file accordinglty.

Sending a simple request

Sending a request is available using the plugin send method.

GigyaSdk.instance.send('REQUEST-ENDPOINT', {PARAMETER-MAP}).then((result) {
      debugPrint(json.encode(result));
    }).catchError((error) {
      debugPrint(error.errorDetails);
    });

Example implementation is demonstrated in the send_request.dart class of the provided example application.

Business APIs

The plugin provides an interface to these core SDK business APIs: login, register, getAccount, getAccount, isLoggedIn ,logOut, addConnection, removeConnection Implement them using the same request structure as shown above. Example application includes the various implementations.

Social login

Use the "socialLogin" interface in order to perform social login using supported providers. The Flutter plugin supports the same *providers supported by the Core Gigya SDK.

Supported social login providers: google, facebook, line, wechat, apple, amazon, linkedin, yahoo.

Embedded social providers

Specific social providers (Facebook, Google) require additional setup. This due to the their requirement for specific (embedded) SDKs.

Example for both Facebook & Google are implemented in the example application.

Facebook

Follow the core SDK documentation and instructions for setting Facebook login. Android documentation iOS documentation

iOS: In addition add the following to your Runner's AppDelegate.swift file:

Gigya.sharedInstance(UserHost.self).registerSocialProvider(of: .facebook, wrapper: FacebookWrapper())

Instead of adding the provider's sdk using gradle/cocoapods you are able to add
the [flutter_facebook_login] plugin to your **pubspec.yaml** dependencies.

Google

Follow the core SDK documentation and instructions for setting Google login. Android documentation iOS documentation

iOS: In addition add the following to your Runner's AppDelegate.swift file:

Gigya.sharedInstance(UserHost.self).registerSocialProvider(of: .google, wrapper: GoogleWrapper())

Instead of adding the provider's sdk using gradle/cocoapods you are able to add
the [google_sign_in] plugin to your **pubspec.yaml** dependencies.

LINE

In order to provider support for LINE provider, please follow the core SDK documentation. Android documentation iOS documentation

WeChat

In order to provider support for WeChat provider, please follow the core SDK documentation. Android documentation iOS documentation

Using screen-sets

The plugin supports the use of Web screen-sets using the following:

GigyaSdk.instance.showScreenSet("Default-RegistrationLogin", (event, map) {
          debugPrint('Screen set event received: $event');
          debugPrint('Screen set event data received: $map');
});

Optional {parameters} map is available.

As in the core SDKs the plugin provides a streaming channel that will stream the Screen-Sets events (event, map).

event - actual event name. map - event data map.

Mobile SSO

The plugin supports the native SDK's "Single Sign On feature".

Documentation:

Andorid

iOS

Please make sure to implement the necessary steps described for each platform.

To initiate the flow run the following snippet.

 GigyaSdk.instance.sso().then((result) {
 // Handle result here.
 setState(() { });
 }).catchError((error) {
// Handle error here.
 });

FIDO/WebAuthn Authentication

FIDO is a passwordless authentication method that allows password-only logins to be replaced with secure and fast login experiences across websites and apps. Our SDK provides an interface to register a passkey, login, and revoke passkeys created using FIDO/Passkeys, backed by our WebAuthn service.

Please follow the platform implementation guides: Swift Android

Additional setup for Android: To support FIDO operations in your application, it is required that the MainActivity class of the application extends the FlutterFragmentActivity class and not FlutterActivity.

Usage example Login with FIDO/WebAuthn passkey:

_loginWithPasskey() async {
    try {
      GigyaSdk.instance.webAuthn.webAuthnLogin().then((result) {
        setState(() {});
      });
    } catch (error) {
      if (error is GigyaResponse) {
        showAlert("FidoError", error.errorDetails);
      }
    }
  }

Register a new FIDO/WebAuthn passkey:

_registerPasskey() async {
    try {
      var result = await GigyaSdk.instance.webAuthn.webAuthnRegister();
      debugPrint(jsonEncode(result));
      showAlert("FIDO success", "passkey registered");
    } catch (error) {
      if (error is GigyaResponse) {
        showAlert("FIDO error", error.errorDetails);
      }
    }

  }

Revoke an existing FIDO/WebAuthn passkey:

 _revokePasskey() async {
    try {
      var result = await GigyaSdk.instance.webAuthn.webAuthnRevoke();
      debugPrint(jsonEncode(result));
      showAlert("FIDO success", "passkey revoked");
    } catch (error) {
      if (error is GigyaResponse) {
        showAlert("FIDO", error.errorDetails);
      }
    }
  }

Resolving interruptions

Much like the our core SDKs, resolving interruptions is available using the plugin.

Current supporting interruptions:

• pendingRegistration using the PendingRegistrationResolver class.
• pendingVerification using the PendingVerificationResolver class.
• conflictingAccounts using the LinkAccountResolver class.

Example for resolving conflictingAccounts interruptions:

GigyaSdk.instance.login(loginId, password).then((result) {
      debugPrint(json.encode(result));
      final response = Account.fromJson(result);
      // Successfully logged in
    }).catchError((error) {
      // Interruption may have occurred.
      if (error.getInterruption() == Interruption.conflictingAccounts) {
        // Reference the correct resolver
        LinkAccountResolver resolver = GigyaSdk.instance.resolverFactory.getResolver(error);
      } else {
        setState(() {
          _inProgress = false;
          _requestResult = 'Register error\n\n${error.errorDetails}';
        });
      }
    });

Once you reference your resolver, create your relevant UI to determine if a site or social linking is required (see example app for details) and use the relevant "resolve" method.

Example of resolving link to site when trying to link a new social account to a site account.

final String password = _linkPasswordController.text.trim();
resolver.linkToSite(loginId, password).then((res) {
     final Account account = Account.fromJson(res);
     // Account successfully linked.
});
