What is awful about Google’s Flutter examples is that they reproduce bad antipatterns that you should never do in a fast, responsive flutter app. While it is nice that they avoid putting such things in the Flutter SDK; it is a real disservice to those learning flutter to have them in the samples included in the flutter SDK.

So what, the hell, am I talking about? Let me show you an example from the samples folder of the SDK install, this is the scaffolding to the material 3 demo:

Notice anything bad yet? Probably not, as lazy coders are all over the place, even at Google! Now to explain the antipattern, I will be explaining flutter SDK internals of how widgets get rendered.
