I released two apps built in dart on flutter. I loved it at the time, but I ran into this issue headlong with both of them. Release v1.0, move on to other things, come back in a year with a new computer to fix a minor bug and I can’t even compile the original release anymore, and had to spend forever rejiggering everything to get it back to the state it was when I left it. I really loved dart, and even flutter, building in it was a breeze. But the churn made the js ecosystem look slow.
You don't get to very rudely accuse someone of giving "fake examples" (why?) and then, later, use weasel words like "in my experience." Perhaps your experience isn't representative of everyone else's.
None of those versions exist, so the example is obviously made up.
Now, it could still be rooted in reality rather than being a complete fabrication. But when all the provided details were made up, it's basically impossible for anyone to check.
