In this two-part series, we will be implementing a simple RSS reader for LWN
using the UI toolkit Flutter. The project recently announced
version 1.20 of the toolkit on August 5. Flutter is a BSD-licensed UI development platform written in
Dart that is backed by Canonical as a new way to
develop desktop applications targeting Linux. Part one will cover some of the
basics of the project and Flutter, with part two building on that work to
focus on building a full interactive UI for the application.
