                ],
              ),
            )

Answer 1

wrap your widget with Center like:

 Center(
            child: Container(
              color: Colors.yellow,
              child: const Icon(Icons.add),
            ),
          ),

the output would look like:

Answer 2

maybe you just make this crossAxisAlignment: CrossAxisAlignment.start, to crossAxisAlignment: CrossAxisAlignment.center, for first Row
