Boden cross-platform framework: Native C++11, native widgets, no JavaScript

GPL means its pretty much unusable...

Yes, it's a way better language than it used to be.

* They added smart pointers that actually work. (std::unique_ptr and std::smart_ptr) Invoking delete is considered a code smell in C++11, and new is considered a code smell in C++14. (because of make_unique and make_shared, added in C++14)

* Dynamic polymorphism (via inheritance) has gone out of style. These days it's templates all the way down, which aren't terrible anymore for a wide variety of reasons that I don't have time to go into.

* Threads and safe locking mechanisms are now actually standardized, so you don't have to use boost::thread. std::async, lambdas, and std::future provide reasonable syntactic sugar around threading, as opposed to manually mucking around with your own thread pool.

* Stuff that used to require library writers to dig around in the bowels of template metaprogramming became a lot easier with `if constexpr` in C++17. Actually that's one of the reasons why templates aren't terrible anymore, sorry for going into it when I said I wouldn't.

Idiomatic C++17 code feels like a completely different language than C++03. Ye olden C++ felt like Java with spike traps and no garbage collector, but idiomatic C++17 feels like... I dunno, Rust without the borrow checker and everything is in an unsafe block. (I'm trying to think of a better example)

(as an aside, there are two different things called "modern c++". I'm pretty sure it's a joke, but it's a terrible one. There's Andrei Alexandrescu's 2001 book Modern C++, and there is are the coding practices that evolved out of the development of C++11/14/17.)

Source: I maintain a ye olden C++ codebase at work, and write modern C++17 in my personal projects. The degree to which they differ is profound. I'm not doing the difference justice.

It draws a comparison between electron, probably the leading contemporary approach for cross platform (albeit not for mobile)

it uses C++ and not QML for the interface, the UI components are actually native, you can use templates, etc.

Except that Flutter is pretty bad on anything that isn’t Android. The “Cupertino” theme needs significant work; it’s significantly worse than even Ionic is.
