Yeah hot reload's just a one-off example that I think is the simplest way to relate the experience of SwiftUI vs. Compose vs. Flutter, though, the first two are long in the rear view mirror, I've been Flutter only for about a year.

Good question -- I don't think its the wrong question? Maybe? :P Tough to phrase on my end too.

I only feel native speaking in iOS or Flutter, even with the Android experience, forgive me: I guess I'd summarize it as "yeah, you're right. if you're wondering if they're ex. calling CoreGraphics on iOS, no" (well, they do, but for text rendering. Not for a red rectangle)

Generally, Flutter Web is rendering into a WebGL surface using Skia -> WASM (2.2 MB download! modern miracle). macOS, iOS, (done) Android (soon) are switching from Skia to Impeller. I think the thrust of your question is "are they still bundling the render engine?" and the answer is yes.

I find the way you phrased it intriguing, in that, before reading your post I'd say drawing to a Skia canvas is as native as you can get. But I realize now that means I was overindexing on "close to the metal", and its apex not-native to say "gimme the framebuffer and i'll take it from there"

I'm a bit picky with design stuff and I loooooove that Skia's bundled and I can rely on it cross platform
