I am new on Flutter and trying to do an app that use camera. So, everything works fine and I am using image_picker lib. Now, I need to add a mask for my user to capture using this mask to position the document (like a overlay) but I can't find anywhere saying how to do that. Does anyone know if it's possible using this lib to do it?
Regards,
I don't think the image_picker can do what you want to do.
Instead of that, you could use the Camera package and put your overlay and the preview of camera in a Stack widget
You can use package https://pub.dev/packages/camera_camera
It provide imageMask attribute
example code https://github.com/gabuldev/camera_camera/tree/master/example/lib
code snippet
Camera(
mode: CameraMode.normal,
imageMask: CameraFocus.rectangle(
color: Colors.black.withOpacity(0.5),
),
)
