Flutter is far more worrying IMO. The Web at least is somewhat standardized and definitely going to last long. There's also nothing intrinsically too slow about it, JS runtimes can definitely be made fast and render engines tend to improve over time, it's also likely we will move on from Electron and it's bloat-packed delivery method. Everything is easily inspect-able as shipped. Compared to that Flutter programs are a huge black-box, completely unportable as delivered not just across platforms but also between accessibility mechanisms it seems. While practically sharing none of the advantages of traditional native toolkits. Responsiveness is dismal, web/desktop targets are basically a PoC, the language and toolkit are so large it's extremely unlikely people will bother maintaining it when Google deprecates it, even if it's 100 times more popular than now. It's just disheartening how people are still keen on developing things far too likely to end in a platform graveyard.
