As far as I understand, the onPurchaseError callback on the PaywallView gets called whenever any of these errors occur: https://www.revenuecat.com/docs/test-and-launch/errors#purchasing-errors.

I’ve been testing this by canceling a purchase. But as far as I can tell nothing inside the function call is getting executed:

onPurchaseError: (error) {

log(“Hello World”);

}

If I look into my logs, I can see that the error was thrown correctly though:
 

E/�Purchases] - ERROR( 4764): BillingWrapper purchases failed to update: DebugMessage: . ErrorCode: USER_CANCELED.null

E/EPurchases] - ERROR( 4764): PurchasesError(code=PurchaseCancelledError, underlyingErrorMessage=Error updating purchases. DebugMessage: . ErrorCode: USER_CANCELED., message='Purchase was cancelled.')

I’m using:
> purchases_flutter 8.6.1
> purchases_ui_flutter 8.6.1

SIDE NOTE:

Observations apply to both V1 and V2 paywalls.

So far, all that I can only confidently say is that onPurchaseComplete and onRestoreComplete are working as intended

Using displayCloseButton and onDismiss doesn’t show a close button either.

Haven’t tested onRestoreError yet.
