The Usercentrics Apps SDK

The Usercentrics Apps SDK is a native Consent Management Platform solution for mobile apps, mobile games & TV applications, that enables the collection, documentation, and management of your user's privacy choices, in order to ensure legal compliance for legal regulations around the world.

Requirements

• Dart 2.17.1 or higher
• Flutter 1.20.0 or higher
• Android 4.1 (API 16) or higher with Kotlin 1.5 or higher
• iOS 11 or higher

To meet the requirements:

Android with Kotlin version lower than 1.5

If you have an incompatible Kotlin version you may see the following error when you run app on Android:

e: Incompatible classes were found in dependencies. Remove them from the classpath or use '-Xskip-metadata-version-check' to suppress errors

This error is easy to solve, you only need to increase the version that is usually in the android/build.gradle file. Use a recent stable Kotlin version, for example: 1.5.31.

Android version lower than 5.0 (API 21)

If you support an Android version lower than 5.0 (API 21) and you don't have the multidex enabled in your project, you may see the following error when you run your app on Android:

D8: Cannot fit requested classes in a single dex file (# methods: 66055 > 65536)

You can change the minimum version of your application to 5.0 (API 21). That configuration is usually in the android/app/build.gradle file. Make sure that minSdkVersion is 21 or higher.

Although Android 5.0 version already supports 99% of all devices, if you still want to have support for Android 4.1 (API 16) you have to do the following:

1. Add the multidex library to your application dependencies that is usually in the android/app/build.gradle file.

implementation "androidx.multidex:multidex:2.0.1"

2. Enable the option in the application build defaultConfig. It is usually in the same android/app/build.gradle file.

multiDexEnabled true

3. Make your application class initialize multidex. There are several options to do that, in Flutter the easiest way is to add it to the manifest. The manifest is usually located at android/app/src/main/AndroidManifest.xml.

android:name="androidx.multidex.MultiDexApplication"

iOS version lower than 11

If you have a iOS target version lower than 11 or you have no version at all (it defaults to version 9) you may see the following error when you run your app on iOS:

[!] Automatically assigning platform `iOS` with version `9.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

This error is easy to solve, you have to do the following:

1. Define or increase the version of your Podfile at least to version 11. It is usually located at ios/Podfile.

platform :ios, '11.0'

2. Run flutter pub get again and open the iOS project using Xcode. It is usually located at ios/Runner.xcworkspace. Now, you have to select the Runner project and change the Deployment Target to the same version.

Integration

Continue to our documentation for a step by step integration guide.

Example

See the example directory for a complete sample app using Usercentrics.

Testing

You can use your own Usercentrics to test the integration or any other functionality.

1. Implement your own UsercentricsPlatform manually or using a mock library such as mockito:

class FakeUsercentrics extends UsercentricsPlatform {
  ...
}

2. Inject your instance in the testing delegatePackingProperty variable:

testWidgets('Initializes Usercentrics', (WidgetTester tester) async {
  final usercentrics = FakeUsercentrics();
  Usercentrics.delegatePackingProperty = usercentrics;

  await tester.pumpWidget(const MyApp());

  expect(usercentrics.initializeCount, 1);
});

3. Clear the instance after the test in order to prevent the tests from interfering with each other:

tearDown(() {
  Usercentrics.delegatePackingProperty = null;
});
