我想要实现的目标如下：

我应该使用带有图标和文本的行吗？

这是我的代码及其输出

    RaisedButton(
          elevation: 10,
          onPressed: () {},
          color: Colors.white,
          child: Padding(
            padding: EdgeInsets.all(10),
            child: Row(
              mainAxisAlignment: MainAxisAlignment.spaceEvenly,
              children: <Widget>[
                Container(
                  height: 55,
                  color: Colors.deepPurple,
                  child: Icon(
                    Icons.settings,
                    color: Colors.white,
                  ),
                ),
                Text(
                  'Settings',
                  style: TextStyle(
                    fontSize: 25,
                  ),
                ),

void main() {
  runApp(MyApp());
