Face Detection in Flutter Using Firebase's ML Kit

In the last piece in this series on developing with Flutter, we looked at how we can implement [image labeling using ML Kit, which belongs to the Firebase family. In this 7th installment of the series, we'll keep working with ML Kit, this time focusing on implementing face detection. Using face detection in Firebase's ML Kit enables you to detect faces in an image, without providing additional data. The face detection algorithm returns rectangular bounding boxes that you can then plot on the detected faces. It's also able to detect key facial landmarks such as eyes, mouth, nose, etc.
