Last time I checked, Dart+Flutter on web renders everything to canvas, which means you lose browser fundamentals: native text selection, accessibility features, screen readers, right click context menus, inspectable DOM elements, and SEO. You also can't use browser dev tools to inspect the UI like you normally would.

The bundle sizes are also quite large compared to typical web frameworks, and you don't get progressive enhancement - it's all or nothing JavaScript.

Maybe things have improved in recent years, but I haven't seen much adoption or buzz around it.
