What are you "Compiling" it against on Android? You must have it set to COMPILE against Android 10+.

Can you send me a sample project?

@jamesmontemagno Thank you for your quick response, I tried changing the compile against Android 10+ and it started working. Also, is there any method or a way to check the purchases in this plugin like getPurchases(); ?

Yes, see documentation: https://jamesmontemagno.github.io/InAppBillingPlugin/CheckAndRestorePurchases.html
