How do you think Flutter now?
Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Flutter's the best choice, now.
I love flutter! It's easy to set up on Linux and Windows. Sorry, I can't say how easy it might be on Mac because I do not have one, but I'm pretty sure it's easy too. Flutter documentation is some of the best you'll find, and there are tutorials to help get you writing some basic apps right away. Community support is solid too. There is even a great discord group: https://discord.gg/N7Yshp4 Best of all, Flutter is multi-platform, supporting Android, iOS, web, and desktop(still in prerelease I believe). This means that with few or no changes to your code, it will work everywhere! Here's a simple flutter web app I made https://flutter-slide-puzzle.netlify.com/#/ and the src if you'd like to check it out https://github.com/pahosler/Flutter-Slide-Puzzle-Hummingbird and finally... https://dartpad.dartlang.org/b6409e10de32b280b8938aa75364fa7b here you can write some code online!
