Flutter isn't a good Electron alternative? Flutter 2.0 just came out with desktop support for osx, windows and linux and will be the main GUI framework for Linux.
Not yet. Or rather, I would say you can use it for simple stuff, like Etcher then it is a reasonable choice. But you wouldn't want to use it for something like Slack yet. Some basic stuff like ctrl-Z in text fields does not work yet. Doing normal desktop things like menus and file dialogs will be a pain.
That said, I am writing a Git desktop client in Flutter and I like it. But I don't expect to finish it for many years so hopefully by then they'll have ironed everything out.
