verifyPurchase abstract method

Future<VerifyPurchaseResult> verifyPurchase({
  1. VerifyPurchaseAppleOptions? apple,
  2. VerifyPurchaseGoogleOptions? google,
  3. VerifyPurchaseHorizonOptions? horizon,
})

Verify a purchase against your own backend. Every VerifyPurchaseResult variant exposes isValid, so entitlement can be gated without inspecting the concrete type. Variants add their own metadata on top: IOS carries receipt/JWS fields, Android carries Play Store receipt fields, and Horizon carries grantTime.
