I saw the Flutter/Dart Google IO presentation and decided I wanted to make a stupid silly Android app. It was pretty easy to get started, but I couldn't find anywhere on how to do a simple lock-screen widget.

Basically I just want an app that periodically polls a JSON API and displays some data on the android lock screen. Is this possible to do with Flutter at the moment?
