          color: Colors.white,
          borderRadius: BorderRadius.all(
            Radius.circular(15),
          ),
        ),
        child: const Icon(
          Icons.outbond_outlined,
          color: Colors.amber,
          size: 50.0,
        ),
      ),
      Container(

        height: 100.0,
        decoration: const BoxDecoration(
          color: Colors.black,
          borderRadius: BorderRadius.all(
            Radius.circular(15),
          ),
        ),
        child: Row(
          // ignore: prefer_const_literals_to_create_immutables
          children: [
            const Icon(
              Icons.call_end_sharp,
              color: Colors.amber,
              size: 30.0,
            ),
            const Text(
              "Skrt",
              style: TextStyle(
                  color: Colors.white,
                  fontSize: 30.0,
                  fontFamily: "Lato"),
            ),
            const Icon(
              Icons.call_end_sharp,
              color: Colors.amber,
              size: 30.0,
            ),
          ],
        ),

Answer 1

use mainAxisAlignment: MainAxisAlignment.center, in your Row

example:

Row(
      // ignore: prefer_const_literals_to_create_immutables
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
        const Icon(
          Icons.call_end_sharp,
          color: Colors.amber,
          size: 30.0,
        ),
        const Text(
          "Skrt",
          style: TextStyle(
              color: Colors.black,
              fontSize: 30.0,
              fontFamily: "Lato"),
        ),
        const Icon(
          Icons.call_end_sharp,
          color: Colors.amber,
          size: 30.0,
        ),
      ],
    ),
