Change opacity of an Icon

Question

I am trying to change the opacity of an icon, when it is present in the code in this format:

child: Icon(Icons.camera_alt),

I want to do it in the same way you can do it with a color:

color: Colors.green.withOpacity(0.25),

Is there a way to do this?

Answer 1

is there anything wrong with this approach?

    Icon(
      Icons.camera_alt,
      color: Colors.green.withOpacity(0.25),
    )
