The pattern I saw from the Youtube video do not define events at all. The data in or out of the bloc are all via streams, and they are all typed as a domain models, like Article in their HackerNews app. I didn’t see any events there. Thoughts?

Just curious, how would you represent some events more complicated than counter increment or decrement? For example, I want to update my room temperature to 24 Celsius degree. How about pass the temperature value as a parameter along with the event object?
