How to convert nv21 CameraImage to Flutter Image

[albertowao]

I can not find a way to convert nv21 frames in the flutter image format ( package:image/src/image.dart )

The Face Detection Package requires to use nv21 format in the CameraController on Android and i need to return the frame with the face detected with face detection package ( a CameraImage object ) but I couldn't find a conversion function from nv21 to flutter format anywhere

i found it for YUV420 and bgra8888, but not nv21

Do you have an example to show?

Thanks!

Example is here:

https://github.com/flutter-ml/google_ml_kit_flutter/tree/master/packages/example

this is how you configure your CameraController:

All of this is in the README:
