“Flutter team members don't actually use Flutter.” (as per the website).
This could explain a lot.
This could explain a lot.
Are you consider a dogfooder if you use the browser? or do you need to lots of write Javascript yourself, etc. to be considered "a user of your product"?
Typically, these are two different sets of people.
So, I don't buy the "always, always" part
Nor are the people doing UI work in Blender going to be able to make Big Bunny.
Nor are the people working on fusion360's parametric system going to build complex mechanical-fluid simulation scenarios.
Flutter is simpler than those, sure, but even in that world you have people that do nothing but fonts & text for their entire careers. They'll know how to do text stuff in flutter, but they'd be lost if you demanded they make a tiktok clone.
Only if you're oblivious to the day-to-day activities of a software project. They work on building a framework, not on using said said framework to build something entirely different that has no bearing in how to build a framework.
You'd be wrong. If your job is maintaining a framework then your focus is on internal details, and how the framework is used would be limited to your concerns in putting up test sets.
Believing that working on a framework gives you equivalent or even similar experience to using said framework in professional settings is a kin to believing that all mechanics are excellent drivers just because they work on cars.
