Opens the Microsoft Store purchase UI for storeId.
storeId must be a non-empty Product Store ID. A null result means the
native Store returned an unknown status value.

Future<StorePurchaseStatus?> makePurchase(String storeId) {
_ensureWindows();
if (storeId.trim().isEmpty) {
throw ArgumentError.value(storeId, 'storeId', 'Must not be empty.');
}
return WindowsIapPlatform.instance.makePurchase(storeId.trim());
}
