openapi-generator version

I’ve tried with the 5.0.0

Details

The generated code compile with no issues, but once you tried to do the call you get an error saying there is no serializer for Uint8list

Suggest a fix

isPrimitiveType should be true for Uint8list, like this they will be no usage of built_value as it’s not needed for Uint8list

Look like this one is fixed too on master ^^ Thanks !

So json.encode probably has no effect for a Uint8List, well that works. I guess this was fixed with https://github.com/OpenAPITools/openapi-generator/pull/8367

You can try the current master.
