Flutter text widget not centered-CodePudding

I am trying to have text centered inside a container. No matter what I did, text is never centered. Here is my code:

Container(
  alignment: Alignment.center,
  width: 47,
  height: 47,
  decoration: BoxDecoration(color: Colors.grey, shape: BoxShape.circle),
  child: Text(
    firstName == null && lastName == null
        ? 'UU'
        : '${firstName[0]}${lastName[0]}'.toUpperCase(),
    style: TextStyle(
      fontFamily: 'AvenirLTStd-Roman',
      fontSize: 18,
      color: Colors.white,
      fontWeight: FontWeight.w300,
    ),
    textAlign: TextAlign.center,
  ),
)

And this is how the screen is generated:

If you notice text is not centered, the bottom part of the container seems to have more "free space" compared to the top. When I open this in widget inspector and highlight Text Widget I see this:

Does anyone know what am I missing here and why is text not centered? I want text to be in the middle of the container and have equal space between top and bottom.

UPDATE:

Using Center widget does not help:
