Yes, this is the kind of things I expect to get better if the tech gets more exposure. If it doesn't then we'll be surely stuck with half-assed solutions for a truly cross-platform dev experience...

Yeah, sorry about the performance. We kinda put that together as an impromptu web demo, like the old ubuntu tour. Flutter for the web is super sucky right now, and lacks a lot of things like accessibility and normal text interaction because it is backed by a canvas element. Ideally as Flutter matures we will be able to improve both the performance and accessibility aspect of it.

FYI I get a blank page when I visit <https://web.dahliaos.io/>.

I see two instances of "Uncaught Error: undefined" in the JS console. Strangely, in a different session I instead see "NoSuchMethodError: J.aH(...) is null" and the empty page has a gray background instead of white. I get similar results in both Firefox 81 and Safari 14 on macOS 10.15. Let me know if you want more info.

There currently is a bug with the localization at the moment. we are working to correct it but it seems to be quite a bug lol

I'll try to evaluate it fairly when it matures some more.

I only see a completely grey page with no content or anything at all, so it doesn't sound like it's just a a11y issue.
