Droidcon SF 2017: Building Modern Cross Platform Apps with Flutter

Link to video - https://www.youtube.com/watch?v=GJyYv58eWOU

In this talk, you will learn about getting started with Flutter - a framework that helps you build modern 60 fps mobile apps for iOS and Android. Flutter uses Dart for its development but prior knowledge or use of Dart is not required to attend this talk. We will look at the various features Flutter provides including topics like building layouts with material design, debugging and more.
