Thank you so much for writing this article! I had just started playing with these animation Patterns and found a few of these concepts confusing.

I read through this article carefully a couple times and it really helped me connect the dots between how each part is interacting with the next.

One question as I’m learning Dart as well: do you think the static lerp constructor on Bar could be a simple factory constructor instead? That way it could be used as a new Bar.lerp(...)?

Looking forward to part 2!
