🚀Setup and Installation

To integrate the Axeptio SDK into your Flutter project, run the following command in your terminal:

flutter pub add axeptio_sdk

This command will automatically add the axeptio_sdk dependency to your pubspec.yaml file and download the latest available version. After running this command, the SDK will be ready for use in your Flutter project.

Alternatively, you can manually add the dependency to your pubspec.yaml under the dependencies section:

dependencies:
  flutter:
    sdk: flutter
  axeptio_sdk: ^latest_version

Android Setup

Minimum SDK Version

To ensure compatibility with the Axeptio SDK, the minimum SDK version for your Flutter project must be set to API level 26 (Android 8.0 Oreo) or higher. To verify and update this setting, open your project's android/app/build.gradle file and check the following:

android {
    defaultConfig {
        minSdkVersion 26 // Ensure this is set to 26 or higher
    }
}

Add Maven Repository and Credentials

In order to download and include the Axeptio SDK, you'll need to configure the Maven repository and authentication credentials in your android/build.gradle file. Follow these steps:

1. Open the android/build.gradle file in your Flutter project.
2. In the repositories block, add the Axeptio Maven repository URL and the required credentials for authentication.

Here is the necessary configuration to add:

allprojects {
    repositories {
        google()
        mavenCentral()
        maven {
            url = uri("https://maven.pkg.github.com/axeptio/axeptio-android-sdk")
            credentials {
                username = "[GITHUB_USERNAME]"  // Replace with your GitHub username
                password = "[GITHUB_TOKEN]"    // Replace with your GitHub personal access token
            }
        }
    }
}

GitHub Authentication

To authenticate and access the Maven repository, you need to provide your GitHub username and personal access token in the username and password fields, respectively. To generate a personal access token (PAT) for GitHub, follow these steps:

1. Visit the GitHub website and navigate to Settings > Developer settings > Personal access tokens.
2. Click on Generate new token and select the necessary permissions (at least read:packages is required to access the repository).
3. Copy the generated token and paste it into the password field in your build.gradle file.

Note: It is recommended to store sensitive information such as your GitHub credentials securely, using environment variables or a secure credential manager, rather than hardcoding them into your build.gradle file.

Sync Gradle

Once you've added the repository and credentials, sync your Gradle files by either running:

bash
flutter pub get

Or manually through Android Studio by clicking File > Sync Project with Gradle Files.

This will allow your project to fetch the necessary dependencies from the Axeptio Maven repository.

iOS Setup

Minimum iOS Version

The Axeptio SDK supports iOS versions 15.0 and higher. To ensure compatibility with the SDK, make sure your project is set to support at least iOS 15.0. To check or update the minimum iOS version, open the ios/Podfile and ensure the following line is present:

platform :ios, '15.0'

This ensures that your app targets devices running iOS 15 or later.

🔧SDK Initialization

To initialize the Axeptio SDK on app startup, select either brands or publishers depending on your use case. The SDK is initialized through the AxeptioService enum and requires your client_id, cookies_version, and optionally a consent_token.

final axeptioSdkPlugin = AxeptioSdk();
await axeptioSdkPlugin.initialize(
    AxeptioService.brands, // Choose either brands or publishers
    "your_client_id",  // Your client ID
    "your_cookies_version",  // Version of your cookies policy
    "optional_consent_token",  // Optionally pass a consent token for existing user consent
);
await axeptioSdkPlugin.setupUI();  // Setup the UI for consent management

The setupUI() function will display the consent management UI once initialized.

App Tracking Transparency (ATT) Integration

The Axeptio SDK does not manage App Tracking Transparency (ATT) permissions. It is the responsibility of the host app to manage the ATT flow, ensuring that the user is prompted before consent management is handled by the SDK.

Steps for Integrating ATT with Axeptio SDK:

1. Add Permission Description in Info.plist: In your iOS project, add the following key to Info.plist to explain why the app requires user tracking:

<key>NSUserTrackingUsageDescription</key>
<string>Explain why you need user tracking</string>

2. Install App Tracking Transparency Plugin:

flutter pub add app_tracking_transparency

3. Request Tracking Authorization: Use the AppTrackingTransparency plugin to request permission before initializing the Axeptio SDK's consent UI. The flow checks the user’s status and takes appropriate actions based on their choice.

try {
  TrackingStatus status = await AppTrackingTransparency.trackingAuthorizationStatus;

  // If the status is not determined, show the system's ATT request dialog
  if (status == TrackingStatus.notDetermined) {
    status = await AppTrackingTransparency.requestTrackingAuthorization();
  }

  // If the user denied tracking, update consent status accordingly
  if (status == TrackingStatus.denied) {
    await axeptioSdkPlugin.setUserDeniedTracking();
  } else {
    // Proceed with the consent UI setup
    await axeptioSdkPlugin.setupUI();
  }
} on PlatformException {
  // On Android, skip ATT dialog and proceed with the UI setup directly
  await axeptioSdkPlugin.setupUI();
}

🗂SDK and Mobile App Responsibilities

The Axeptio SDK and your mobile application each have distinct responsibilities in the consent management process:

Mobile App Responsibilities:

1. Implementing ATT Flow
   Your app must handle the App Tracking Transparency (ATT) permission request and manage the display of the ATT prompt at the appropriate time relative to the Axeptio CMP.

2. Privacy Declaration
   The app must declare data collection practices accurately in App Store privacy labels.

3. Handling SDK Events
   The app should listen for events triggered by the SDK and adjust its behavior based on user consent status.

Axeptio SDK Responsibilities:

1. Consent Management UI
   The SDK is responsible for displaying the consent management interface.

2. Storing and Managing User Consent
   It stores and manages consent choices across sessions.

3. API Integration
   The SDK communicates user consent status through its API endpoints.

Note: The SDK does not manage ATT permissions. You must handle this separately as shown above.

Retrieving and Managing Stored Consents

To retrieve stored consent choices, use UserDefaults (iOS) or SharedPreferences (Android) with the shared_preferences package.

Dart Example

import 'package:shared_preferences/shared_preferences.dart';

// Access stored consents
SharedPreferences prefs = await SharedPreferences.getInstance();
String userConsent = prefs.getString('axeptio_consent');

Displaying the Consent Popup on Demand

If needed, you can display the consent popup manually by calling the following method:

axeptioSdk.showConsentScreen();

This is useful if you want to show the popup at a specific moment based on app flow or user behavior.

Sharing Consents with Web Views

For publishers, the SDK provides a feature to share the user's consent status with web views by appending the Axeptio token as a query parameter.

final token = await axeptioSdk.axeptioToken;
final url = await axeptioSdk.appendAxeptioTokenURL(  
  "https://myurl.com",  
  token,  
); 
// Will return: https://myurl.com?axeptio_token=[token]

This feature ensures that consent status is properly communicated across different parts of the application, including web content.

🔄Clearing User Consent

If necessary, you can clear the user’s consent choices by invoking the following method:

axeptioSdk.clearConsent();

This will reset the consent status, allowing the user to be prompted for consent again.

Event Handling and Customization

The Axeptio SDK triggers various events that notify your app when the user takes specific actions related to consent. Use the AxeptioEventListener class to listen for these events and handle them as needed.

Example Event Listener Implementation:

var listener = AxeptioEventListener();

// Event triggered when the user closes the consent popup
listener.onPopupClosedEvent = () {
  // Retrieve consents from SharedPreferences/UserDefaults
  // Handle actions based on the user's consent preferences
};

// Event triggered when Google Consent Mode is updated
listener.onGoogleConsentModeUpdate = (consents) {
  // Handle updates to Google Consent Mode status
  // Perform specific actions based on updated consents
};

// Add and remove event listeners as necessary
var axeptioSdk = AxeptioSdk();
axeptioSdkPlugin.addEventListener(listener);
axeptioSdkPlugin.removeEventListener(listener);

By following this guide, you'll be able to integrate the Axeptio Flutter SDK effectively into your app, providing comprehensive consent management and ensuring compliance with privacy regulations.
