I want to add face contour in expo-face-detector

This is my code :slight_smile:

List<PointF> lowerLipUpperContour = face.getContour(FaceContour.LOWER_LIP_TOP).getPoints();
List<PointF> upperLipLowerContour = face.getContour(FaceContour.UPPER_LIP_BOTTOM).getPoints()

Bundle points = new Bundle(2);
points.putDouble("x", lowerLipUpperContour.get(5).getX());
points.putDouble("y", lowerLipUpperContour.get(5).getY());
encodedFace.putBundle("lowerLipUpperContour",points);```

I get the following error : 
error: cannot find symbol
    points.putDouble("x", lowerLipUpperContour.get(5).getX());
