Revenuecat products are null while testing and trying to design paywall - flutter

Question

Trying to design the paywall following the example flutter app provided by RevenueCat and when I configure the offering are always null.
Running version purchases_flutter: ^1.1.1
Offerings.current = NULL <- this is my problem.
In Google console the app ids are: com.sampleapp.moments.1month, com.sampleapp.moments.yearly and are both active.
How can I go about testing and designing a paywall page if the offerings are null? How can I get this to work?
Error code, following the example: https://github.com/RevenueCat/purchases-flutter/blob/develop/example/lib/main.dart
[ ] D/[Purchases] - DEBUG(14481): Requesting products with identifiers: com.sampleapp.moments.1month, com.appname.moments.yearly

Answer 1

If your products, offerings, or packages are empty it's most likely related to a configuration or setup issue in Apple/Google.
On Android, you need to publish your app to a closed track before you can fetch any products or test purchases - that could be what's going on here.
There is a a handy guide here that outlines the common reasons for this here: https://support.revenuecat.com/hc/en-us/articles/360041793174-Why-are-my-products-offerings-or-available-packages-empty-
