Flutter - Adapty SDK Installation and configuration

Adapty SDK includes two key modules for seamless integration into your mobile app:

  • Core Adapty: This essential module is required for Adapty to function properly in your app.
  • AdaptyUI: This module is required if you’re using the Adapty Paywall Builder—a no-code, user-friendly tool for creating cross-platform paywalls. With a visual constructor right in the dashboard, you can build paywalls that run natively on devices and are designed to deliver high performance with minimal effort. The module is installed automatically with the Adapty SDK, but you can leave it deactivated if you don’t need it.

    pubspec.yaml
    dependencies:
    adapty_flutter: ^3.2.3

  2. Run:

    Bash
    flutter pub get

Configure Adapty SDK​

You only need to configure the Adapty SDK once, typically early in your app's lifecycle.

        await Adapty().activate(
            configuration: AdaptyConfiguration(apiKey: 'YOUR_API_KEY')
              ..withLogLevel(AdaptyLogLevel.debug)
              ..withObserverMode(false)
              ..withCustomerUserId(null)
              ..withIpAddressCollectionDisabled(false)
              ..withIdfaCollectionDisabled(false),
        );
    } catch (e) {
        // handle the error
    }

    final mediaCache = AdaptyUIMediaCacheConfiguration(
        memoryStorageTotalCostLimit: 100 * 1024 * 1024, // 100MB
        memoryStorageCountLimit: 2147483647, // 2^31 - 1, max int value in Dart
        diskStorageSizeLimit: 100 * 1024 * 1024, // 100MB
    );

    await AdaptyUI().activate(
        configuration: AdaptyUIConfiguration(mediaCache: mediaCache),
        observer: <AdaptyUIObserver Implementation>,
    );
} catch (e) {
    // handle the error
}
