flutter - Dart built_Value, BuiltList error in serializer - Arguments of a constant creation must be constant expression

I have the following json object

I have created the following object model using built_value

And the following seralizer for json deserialization:

The login object model worked fine and is working as expected but when I added the NotificationList to SerializersFor, the serializer.g.dart file started throwing errors. I am getting this error message for BuiltList in the serializers.g.dart file

Arguments of a constant creation must be constant expression

Invalid constant value

Undefined name 'BuiltList'

Undefined class 'ListBuilder'

On trying to compile I am getting this error which says the same thing

Not sure where I am going wrong or what the issue could be. Using the following versions for built_value and built_collection

This is the serializer.g.dart file generated:

Any help will be greatly appreciated.
