Flutter on the web is absolutely insane. For those who don't know, it basically strips away everything and wraps it in a big terrifyingly complex mess of code and renders everything in a canvas. Flutter advocates like to claim that that's "only a fallback" for when things get complex but as far as I can tell the vast majority of things (including the simplest examples from Flutter itself) force the entire thing into canvas: it's basically Flash 2.0, but worse.

I seriously hope that Flutter fades. It's very dangerous in many ways. Even ignoring the huge downsides of basically having a new Flash, consider this: the massive Flutter layer is, surprise surprise, yet another Google project that is magically _significantly_ slower in Firefox. I don't mean a small difference here, I mean that on a brand new fancy flagship I tested on, Flutter in Chrome is buttery smooth and Flutter in Firefox is a miserable, laggy experience. If it gets popular, this will become yet another reason pushing people off Firefox and cementing Google's dominance of the web.

Flutter is a very, very dangerous thing.
