Accessibility is a first class citizen in flutter.

It's the equivalent of having a company that actively discriminates against everyone not passing a internally developed test to check whether you are a "neurotypical" and then respond to criticism by pointing at the wheelchair ramp you installed on one of your entrances.
If I can't copy paste words from your websites to put them into a translator, if I can only use your website when I use one of the two corporate-affiliate-selected screen readers (not even platform-agnostic ones), when I can't look at your website from anything that does not have 4+ cores and a 4G or better connection...saying accessiblity is a "first class citizen" or even citizen at all is laughable at best.
That is attacked through very different means. For example, FB being free and ad funded addresses that issue; but this is a business model and not a technological standard. Society subsidizing technology is another possibility. But these very serious issues of access and the solutions to negotiate with them are very different from purely technical solutions to access.
If your website is unreadable in view-source:, it's probably inaccessible in some way. It's not hard to make an accessible website. If it's hard to make that accessible website look the way you want? Tough luck; hire a competent web designer, or scale back your artistic vision, because you sure ain't sacrificing the ability for people to actually use your website for some pretty colours, are you now?
