Hey I got the same error. I solved it by these steps.

go to native kotlin code of the plugin.
goto this file path: flutter_inapp_purchase-5.4.1/android/src/main/kotlin/com/dooboolab/flutterinapppurchase/AndroidInappPurchasePlugin.kt
go to private fun buyProduct() method in the file
go to line number 514
remove below code from line 514 to 522 if (offerToken == null) { offerToken = selectedProductDetails.subscriptionOfferDetails!![0].offerToken } val productDetailsParamsList = listOf(ProductDetailsParams.newBuilder() .setProductDetails(selectedProductDetails) .setOfferToken(offerToken) .build())
replace the code with this code. if (offerToken == null) { offerToken = selectedProductDetails.subscriptionOfferDetails?.get(0)?.offerToken } val productDetailsParamsList = listOf( if(offerToken == null) ProductDetailsParams.newBuilder() .setProductDetails(selectedProductDetails) .build() else ProductDetailsParams.newBuilder() .setProductDetails(selectedProductDetails) .setOfferToken(offerToken) .build() )
restart the app and boom.
