This post makes very big claims based on a very basic application that doesn't seem to be much more than a few toggle buttons and a couple of animations thrown in..

That's 90% of non-game apps. Most apps could be written using web-based tech (React Native, Flutter, PWA, whatever), and because they're so simple they should be very fast and very small. Where an app that's a few toggles and animations is slow or janky it's a sign that the developer screwed up rather than a problem that would be solved by going native - the dev would screw up regardless of the tech they used.

Some apps that have extensive design or animation work benefit from being native, and there are some things that are painful to do using web tech like custom camera work or things that use the secure enclave in weird ways, but if you're not doing those things then web should be fine.

React native and flutter are very, very different from a PWA.

While a PWA is a web app, react-native renders actual native components, and flutter has its own rendering engine. I wouldn't call them "web-based" tech

I wouldn't call them "web-based" tech

They're not web-based under the hood, but the code that the developer writes to drive them is very much in the ballpark of a web developer - JS, React, TS, Webpack, etc. That's why they're classified as "web-based" or "web hybrid" rather than "native".

Flutter has very little to do with web tech though.
