How to center both?

Question

I am learning flutter now, and I am making this app very simple and I would like to know how I can centralize these 2 widgets in the center and regardless of the size of the number always stay centered, tried in several ways but I can not at all, follow the code:

All this is inside a Column

Row(children: [
   Expanded(
      child: RotatedBox(
                 quarterTurns: 3,
                 child: Text(
                     "Pessoas", 
                      style: TextStyle(
                          color: Colors.white, fontSize: 40.0),
                            ),
                          ),
                        ),
                        Text(
                          "$countPeople",
                          style:
                              TextStyle(color: Colors.white, fontSize: 150.0),
                          textAlign: TextAlign.center,
                        ),
                      ]),

If you want to center in the center, you can use the screen to use the mainAxisAlign property, but if you want the two items with different heights to center on each other, use cross-Axis-center. I don’t quite understand your question, if not this, add more information so I can cage you.
