Snapchat Filters with Flutter's CustomPainter and MLKit

In this talk, we will build a camera app in Flutter that can detect your face using ML Kit's face detection API and explore how easy it is to build custom Snapchat-like image filters using Flutter's own Canvas API, Custom Painter and a bit of easy mathematics. By the end, you will leave this talk with our demo app that can take Vikings special selfies that you can share with your Twitter audience.
