Real time face detection in flutter app

[Ian Leshan]

Hello,

I am currently developing an app that requires real time face detection. Right now I have the mlkit library in the app and I am using the firebase face detector. At the moment, it produces an error every time I try to detect a face from file: 

DynamiteModule(13840): Local module descriptor class for com.google.android.gms.vision.dynamite.face not found.

As for the real time part, I tried using the RepaintBoundary in flutter to get a screenshot of the camera widget (almost)every frame and convert it into a binary file for face detection. But for some reason, flutter crashed every time I tried to screenshot the camera widget. It worked for other widgets.

After coming across both of these problems and spending quite a while trying to solve them, I've been thinking about just doing the camera part of the app in android/iOS native code(I would do this with OpenCV so that I can have real time detection). Is there a way I could use platform channels to implement a camera view in kotlin and swift and import that to a flutter widget? Or is there another easier way to implement this?

Thanks,

Ian.

Hi Ian,

I should be able to help with your first bug. Are you using the mlkit plugin or firebase_ml_vision plugin?
