This talk is an intro to Flutter, a popular framework for mobile app devel. Using the example of a Christmas-themed novelty game I wrote from scratch for Android and iOS, I demonstrate the steps required to build a functional Flutter app. Flutter allows to develop cross-platform apps for Android, iOS, Web, Linux, and more from a single code base. It has gained a lot of traction since its launch by Google in 2017 and is widely considered mature enough for production. Flutter apps compare well to their native cousins and are straightforward to develop. Together, this makes Flutter uniquely suited for MVPs (minimum viable products), where the goal is to build demos for multiple platforms with limited resources. The talk does not require prior Flutter knowledge but a basic understanding of the app development process will help. Listeners will not only learn about Flutter but will also gain insights into the German Christmas tree industry. How the two are related? Find out in the talk…
