What he said. Flutter's widget set is neither HTML-rendered like hybrid or native OS widgets like Xamarin or React Native (or NativeScript) but use a C++ layer of its own. Putting that on Android was no surprise; getting it past the censors at Apple is a little more surprising. There's also no reason this widget layer cannot be ported to macOS, Windows, and Linux... I'll let y'all's imaginations run with that for a bit. I told a wicked-smart colleague of mine about Flutter in general; a couple weeks later he came back and said he had written a sample app in Flutter and then decompiled the resulting IPA and APK files and examined the assembly. His report was that it looked very similar to apps he had written in C++ (like I said, he's wicked-smart).
