一屏多种网格布局

当我创建 XML 资源目录然后显示错误“找不到模块模块的资源目录”时，如何解决 flutter 项目中的此错误？

我正在使用以下代码：如何在flutter中设置这种布局

Container(
      height: 200.0,
      decoration: new BoxDecoration(
        color: Colors.white,
        shape: BoxShape.circle,
      ),
      child: Center(
        child: Stack(
          children: <Widget>[
            Icon(Icons.play_arrow, color: Colors.blue, size: 200.0,)
          ],
        ),
      ),

    );
