I need to be able to scan inverted barcodes (white on dark background). I know that firebase mobile vision does not support this feature. Perhaps it is possible to invert the image from the camera and pass it to the mobile vision api. Any ideas how to achieve this?

did you find any package or solution for that? I'm trying to scan an inverted data matrix code but still no clue.

@atarana I've solved that long ago using google ml kit, I took frames using flutter camera preview and manipulated the YUV image bytes taken by the stream and sent it to the ml kit to scan it and it worked..
that's the only way I found
