Setup & Authentication

With Amity UIKit 2.3, we have introduced a new way to Authentication process. Just follow the guide below.

Adding required permissions

Your app may require the following permissions to work properly;

  1. Camera access

  2. Microphone access

  3. Photo library usage access

Before submitting your application to the store, please make sure the following permissions are already granted. Here are the steps to ask for permission.

Locate the info.plist file and add:

  1. NSCameraUsageDescription

  2. NSMicrophoneUsageDescription

  3. NSPhotoLibraryUsageDescription

Setup API key

AmityUIKit requires an API key. You need a valid API key to begin using the UIKit. Please find your account API key in Amity Social Cloud Console.

After logging in Console:

  1. Click Settings to expand the menu.

  2. Select Security.

  3. In the Security page, you can find the API key in the Keys section.

Certainly! The provided code snippet demonstrates how to set up and authenticate using the Amity UIKit for Flutter. Let's break it down into a step-by-step guide:

Step 1: Initialize Amity SDK

First, you need to initialize the Amity SDK in your main function. This is crucial for setting up the SDK before your Flutter app starts running.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  AmitySLEUIKit().initUIKit("YOUR_API_KEY", "REGION");
  runApp(const MyApp());
}

  • WidgetsFlutterBinding.ensureInitialized(): Ensures that Flutter bindings are initialized.

  • AmitySLEUIKit().initUIKit("YOUR_API_KEY", "REGION"): Initializes the Amity UIKit with your API key and region. Replace "YOUR_API_KEY" and "REGION" with the actual values.

Step 2: Wrap MaterialApp with AmitySLEProvider

In your main app widget (here, MyApp), wrap the MaterialApp with AmitySLEProvider. This provider is necessary for the Amity UIKit to function properly throughout your app.

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return AmitySLEProvider(
      child: Builder(builder: (context2) {
        // Configuration and MaterialApp code goes here
      }),
    );
  }
}

Step 3: Implement Authentication

In your InitialWidget class, implement a button to handle the login process with Amity.

ElevatedButton(
  onPressed: () {
    AmitySLEUIKit().registerDevice(context, "USER_IDENTIFIER");
  },
  child: const Text("Login to Amity"),
),

  • Replace "USER_IDENTIFIER" with the identifier of the user who is logging in.

Step 4: Navigating to UIKit Screens

The code provides examples of how to navigate to various screens provided by the Amity UIKit, like channel lists, chat rooms, and global feeds.

Navigator.of(context).push(MaterialPageRoute(
  builder: (context) => const CommunityPage(),
));

Final Step: Running Your App

Once these steps are implemented, you can run your Flutter app. The Amity UIKit should be integrated and functioning according to the setup in your main.dart.

Remember to replace placeholders like "YOUR_API_KEY", "REGION", and "USER_IDENTIFIER" with actual values specific to your Amity UIKit setup.

Register device for push notifications

Registering your app for push notifications will require a device token as a parameter.

Amity's UIKit does not manage:

  • User-facing requests for push notifications and authorizations

  • The creation and refreshing of push notification tokens

It's up to your app to take those steps and pass the device token.

AmitySLEUIKit().registerNotification("asdasdasdasd",(isSuccess, error) {});

Unregister

In the event that your user logs out, you should explicitly unregister the user from the SDK as well, to prevent the current device from receiving any unnecessary or restricted data.

AmitySLEUIKit().unRegisterDevice();

Unregistering a device is a synchronous operation. Once theunregisterDevice method is called, the SDK disconnects from the server and wipes out user session.
