Face Detection Using Firebase ML-Kit

Steps

• First create a Firebase project and add the image_picker and firebase_ml_vision dependencies.
• Use image_picker to get the image from camera/gallery & convert it into a format that can be understood by ML Kit.
• Pass the converted image to the detector and get it to scan the image for possible faces.
• The face detector will return a list of Face class which contains the Rect coordinates.
• The Painter will then use these coordinates to draw a rectangular box around the faces using these coordinates
