Flutter is Google's UI framework for building iOS, Android, Fuchsia, the web and now more desktop apps. The promise of Flutter is that developers can target multiple platforms with a single code base.

With the Flutter 3 release, the platform now supports iOS, Android and web apps, as well as Windows, macOS and Linux desktop apps, all as part of Flutter’s stable release.

Google is partnering with the Ubuntu Desktop team at Canonical to bring Linux support to its open source UI framework Flutter.
