Home Screen
所以我试着重新创建一个有点像iOS应用商店主页的布局。我想知道如何在“主页”标题旁边添加一个小的个人资料图标，如所附截图所示。我试着使用某些对齐方式，但似乎不起作用。有什么建议吗？我刚刚附上了下面的代码作为参考

return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        resizeToAvoidBottomPadding: false,
        body: Container(
          width: double.infinity,
          decoration: BoxDecoration(
            gradient: LinearGradient(
              colors: [
                Colors.blue[900],
                Colors.blue[300],
              ],
            ),
          ),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              SizedBox(height: 30),
              Padding(
                padding: EdgeInsets.all(20),
                child: Column(
                  crossAxisAlignment: CrossAxisAlignment.start,
                  children: <Widget>[
                    SizedBox(height: 20),
                    Text(
                      'Home',
                      textAlign: TextAlign.center,
                      style: TextStyle(
                        color: Colors.white,
                        fontSize: 50,
                        fontWeight: FontWeight.bold,
                      ),
                    ),
                    SizedBox(height: 50),
                    Container(
                      padding: EdgeInsets.fromLTRB(80, 110, 80, 0),
                      decoration: BoxDecoration(
                        borderRadius: BorderRadius.all(
                          Radius.circular(20),
                        ),
                        color: Colors.white,
                      ),
                    ),
                    SizedBox(height: 30),
                    Container(
