+1 Its not optional since the introduction of null safety - null used when the type is non-nullable throws an exception. Any null attribute used in a model's constructor will fail unless the class attribute (of type T) is declared nullable (as T?). This is a severe limitation.
A quick fix might be to use nullable type everywhere.
The current release of https://github.com/OpenAPITools/openapi-generator seems to work for null-safe Dart, if you're in a hurry.
