How to Add Face Detection to your Expo React Native App - Recognize Smiling/Eyes Shut and More!

Hi everyone!

Today I want to show you how to add face detection to your expo react native apps for Android and Apple devices using the expo-face-detector and expo-camera packages. You will learn how to add a camera to your iOS and Android apps and pass face detector options to the camera to get information about on camera faces. You can gain insights into positions of certain facial features, whether a face is smiling, where eyes are open or shut. Also you will be able to track faces between frames and recognize multiple faces on camera and their individual features.

For expo-face-detector settings please see the expo documentation:
https://docs.expo.dev/versions/latest...

For expo-camera documentation please see the documentation on expo:

// ABOUT ME
My name is Chelsea and I started studying software engineering in 2010. I have been working commercially full time since 2014 and have been in various positions from graduate developer to tech lead to solution architect.
I'm a full stack developer with a lot of experience in C# and Javascript but my passion is for mobile development; specifically native iOS development and cross platform using React Native.

I always have many things on the go and am always trying out a new side hustle and failing at it; perhaps you can learn from my mistakes!
