Answer 1

Try to remove your second Column Widget and give TextAlign.center

Refer TextAlign here and here

Text(
          "Please enable device location to ensure accurate nearby salons location for easy search",
          style: TextStyle(
            
              fontWeight: FontWeight.w400,
              fontSize: 17,
              color: Colors.black),
              textAlign: TextAlign.center,
        ),
