Can't set Rx variable because runtimeType is different

Question

I have a GetX app and I want to sync the CustomerInfo from Revenuecat with my app (I wasn't sure if this information is necessary so I included it). I basically add a listener to do this:

Purchases.addCustomerInfoUpdateListener((CustomerInfo info) {
  print(info.runtimeType);
  customerInfo.value = info;
});

The type of customerInfo is a Rx variable on my GetX controller that looks like this: Rx<CustomerInfo?> customerInfo = null.obs;. But this doesn't work, because the runtimeType of ìnfo is _$CustomerInfoImpl and not CustomerInfo. I tried casting the value but that doesn't work either. I always get this error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: type '_$CustomerInfoImpl' is not a subtype of type 'Null' of 'v'

For anyone who has the same problem, I found a solution: Instead of using Rx<CustomerInfo?>, you have to use Rxn<CustomerInfo>.
