Out of interest, do you know many seriously vision-impared people?
Windows, and Mac OS X in particular, have quite good support for accessibility if you use their built-in GUI systems, and unified UIs are often (not always, vscode and chrome are quite good, for example), very bad, sometimes just a black square as far as accessibility goes.
Many cross platform frameworks have good accessibility support, not sure what that has to do with native platforms, as the cross platform solutions simply hook into the native platform accessibility APIs anyway.
I didn't know flutter had such good support, and I'm very happy to hear about it!
Unfortunately, most cross-platform frameworks have awful accessibility support, I've looked at various in the past and just found failure after failure. I am now going to look harder at flutter.
