PyQT with QML / QT Quick is another option for cross-platform (Android, iOS, Windows, Mac, Linux) development, but the widgets aren't native. It's closer to Flutter in that way.
QT Widgets, in contrast, do have native-looking widgets for Mac and Windows. You can use it with Python instead of C++, but it's a bit of a pain, and most of the Qt community seems to be moving towards QML, which is a far better developer experience.
