I have implemented in app purchases (IAP) as per in_app_purchase package example
I am able to buy a product from the store (I only have one set up). But when it comes to testing "user has a new phone" scenario, the restore purchases does not seem to work. No error either.
I've implemented this in a provider pattern. Store connection is initialized like this:
_isStoreAvailable = await _inAppPurchase.isAvailable();
Purchasing is implemented this way:
Future<void> initializePurchase() async {
ProductDetailsResponse response =
await _inAppPurchase.queryProductDetails(_productIds);
if (response.notFoundIDs.isNotEmpty) {
// Handle the error.
print("not found product in store!)");
} else {
PurchaseParam purchaseParam = PurchaseParam(
productDetails: response.productDetails.first,
);
_inAppPurchase.buyNonConsumable(purchaseParam: purchaseParam);
}
}
I listen for changes using this code:
final Stream<List<PurchaseDetails>> purchaseUpdated =
_inAppPurchase.purchaseStream;
_subscription =
purchaseUpdated.listen((List<PurchaseDetails> purchaseDetailsList) {
_listenToPurchaseUpdated(purchaseDetailsList);
}, onDone: () {
_subscription.cancel();
}, onError: (error) {
print("listen error: $error");
});
...and this
Future<void> _listenToPurchaseUpdated(
List<PurchaseDetails> purchaseDetailsList) async {
for (final PurchaseDetails purchaseDetails in purchaseDetailsList) {
if (purchaseDetails.status != PurchaseStatus.pending) {
if (purchaseDetails.status == PurchaseStatus.error) {
//handle error
} else if (purchaseDetails.status == PurchaseStatus.purchased ||
purchaseDetails.status == PurchaseStatus.restored) {
setLicense(StoreLicenseStatus.paid);
notifyListeners();
if (purchaseDetails.pendingCompletePurchase) {
await _inAppPurchase.completePurchase(purchaseDetails);
}
}
}
}
}
User can request purchases to be restored using this code:
Future<void> restorePurchases() async {
await _inAppPurchase.restorePurchases();
}
Everything except restore works. I can buy a product, clear data, and when I start the app again, if I try to buy, I get a message from the store "you already own this item". So the store recognizes that the product was already purchased, great! But when I click "restore" nothing happens.
Am I missing something here?
This is on an emulator (Pixel 4 API 32), also on a real device.
