[Star wars] Are there any type 2 or 3 civilizations?

It seems to me like there should be type 2 civilizations and things like Dyson arrays and the such but they're never really talked about and there are plenty of people throughout the Galaxy that barely even live at the technology that we have today. I know that in Legends there's things like the Star forge which would most definitely be like a type 2 energy source.

The problem with stars technology in the sense of its scaling is with its power generation. 

Whatever is powering literally everything is far more energy dense than anything we have ever seen. So why build a dyson sphere if some reactor will deliver the same amount of power>
