purchase method
Starts a purchase after configuration.
Cancellation is a domain result and must not be reported as a transport exception. Implementations must not both navigate and return a redirect URL unless their documented integration contract explicitly requires it.
Implementation
Future<InappifySdkResult<PurchaseResult>> purchase(
InappifyPurchaseRequest request,
) async {
return _unsupported<PurchaseResult>('purchase');
}
