I tried it as well for a Flutter application to see what it would come out with for an OAuth 2.0 code section for a prototype I was working on... and it was deprecated code that would not even compile. Granted Flutter has a lot of changes between versions. This is not going to work for not so popular languages, so there is a niche in those, and it syphons code from public (possibly private) repos to come up with a solution. This can be useful for adding features on production code for popular languages, not sure on new challenging prototypes. Maybe try it on using it for a C++ Bluetooth communication layer section of code and see how that works, that would make for a good test.
