The main problem in projects like flutter is to always focus on the "new". If you focus on the new without stabilizing the existing basic features, you will accumulate thousands of problems. If the same path is followed in this new project, I think the result will be the same. There is still no clear update on issues opened years ago. and most are pretty basic needs.
I don't think good engineering is a soup of confusion like the one in this article. simple is beautiful. And I think good engineering is associated with simplicity.
