Implement Observer mode in Flutter SDK

If you already have your own purchase infrastructure and aren't ready to fully switch to Adapty, you can explore Observer mode. In its basic form, Observer Mode offers advanced analytics and seamless integration with attribution and analytics systems.

If this meets your needs, you only need to:

  1. Turn it on when configuring the Adapty SDK by setting the observerMode parameter to true. Follow the setup instructions for Flutter.
  2. Report transactions from your existing purchase infrastructure to Adapty.

Observer mode setup​

Turn on the Observer mode if you handle purchases and subscription status yourself and use Adapty for sending subscription events and analytics.

important

When running in Observer mode, Adapty SDK won't close any transactions, so make sure you're handling it.

main.dart
await Adapty().activate(
  configuration: AdaptyConfiguration(apiKey: 'YOUR_PUBLIC_SDK_KEY')
    ..withObserverMode(true) // Enable observer mode
    ..withLogLevel(AdaptyLogLevel.verbose),
);

Parameters:

ParameterDescription
observerModeA boolean value that controls Observer mode. The default value is false.

Using Adapty paywalls in Observer Mode​

If you also want to use Adapty's paywalls and A/B testing features, you can — but it requires some extra setup in Observer mode. Here's what you'll need to do in addition to the steps above:

  1. Display paywalls as usual for remote config paywalls.
  2. Associate paywalls with purchase transactions.
