Present flows in Observer mode - Unity

If you’ve customized a flow or paywall using the builder, you don’t need to worry about rendering it in your mobile app code to display it to the user. Such a flow or paywall contains both what should be shown and how it should be shown.

In Observer mode, the SDK does not make purchases for you. When a user taps the purchase or restore button in an Adapty-rendered flow or paywall, the SDK calls your IAdaptyUIObserverModeResolver instead — perform the purchase or restore with your own code there.

1. Implement the IAdaptyUIObserverModeResolver interface:

   using System;
   using AdaptySDK;
   
   public class MyObserverModeResolver : IAdaptyUIObserverModeResolver
   {
       public void FlowViewDidInitiatePurchase(
           AdaptyUIFlowView view,
           AdaptyPaywallProduct product,
           Action onStartPurchase,
           Action onFinishPurchase
       )
       {
           onStartPurchase(); // the view shows its loading indicator
           // make the purchase with your own code,
           // then report the transaction to Adapty and call:
           onFinishPurchase(); // the view hides the loading indicator
       }
   
       public void FlowViewDidInitiateRestore(
           AdaptyUIFlowView view,
           Action onStartRestore,
           Action onFinishRestore
       )
       {
           onStartRestore();
           // restore purchases with your own code, then:
           onFinishRestore();
       }
   }

   The FlowViewDidInitiatePurchase method informs you that the user has initiated a purchase, and FlowViewDidInitiateRestore — that the user has initiated a restore. Trigger your custom purchase or restore flow in response.

   Also, remember to invoke the following callbacks to notify AdaptyUI about the process of the purchase or restore. This is necessary for proper flow behavior, such as showing the loader, among other things:

   Callback	Description
   onStartPurchase()	The callback should be invoked to notify AdaptyUI that the purchase is started.
   onFinishPurchase()	The callback should be invoked to notify AdaptyUI that the purchase is finished.
   onStartRestore()	The callback should be invoked to notify AdaptyUI that the restore is started.
   onFinishRestore()	The callback should be invoked to notify AdaptyUI that the restore is finished.

   The flow stays open while your code runs — dismiss it yourself after a successful purchase or restore.

2. Register the resolver before presenting any screen:

   Adapty.SetObserverModeResolver(new MyObserverModeResolver());

   Without a registered resolver, the flow view has no way to hand the purchase over to your code, and nothing happens when the user taps the purchase button.

3. Create and present the flow view as usual: fetch the flow and create its view, then present it. No extra parameters are needed — once the resolver is registered, every Adapty-rendered flow or paywall routes purchases and restores through it.
