'Face Detection in Preview Camera Feed on Flutter
How do we "draw a square" on detected faces on camera preview feed in Flutter? Is there a cross platform solution to this?
Flutter provides a Camera Plugin, but is there a way for us to draw a square box detecting faces on the preview feed? Any thoughts on this please?

SOMETHING LIKE THIS EXAMPLE CAMERA PREVIEW FEED

Firstly, get the image data. This can be done by either using the camera plugin's output, or even directly communicate with the SurfaceView/TextureView.
Secondly, run face detection algorithm. If you do not need cross-platform, https://medium.flutterdevs.com/face-detection-in-flutter-2af14455b90d?gi=f5ead7c6d7c9 MLKit sounds good. If needing cross-platform, you can use Rust algorithms like https://github.com/atomashpolskiy/rustface and bind Rust code to Flutter via https://github.com/fzyzcjy/flutter_rust_bridge. Or, use C++ face detection algorithms and bind to Flutter (though setup may be a bit harder).
Lastly, once you know the face, draw a box around it. For example, Container widget.
