Flutter 给部件加圆角报错

flutter 给小部件加圆角

报错:Cannot provide both a color and a decoration The color argument is just a shorthand for "decoration: new BoxDecoration(color: color)".

达到这种效果.png

错误代码
child: Container(
                height: 40,
                color: Colors.white,
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(6.0),
                  color: Colors.white,
                ),

                                ![报错表述的意思是不能同时提供颜色和装饰.png](https://upload-images.jianshu.io/upload_images/1949959-eae7638fb30ca1af.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)

解决办法去掉:只能去掉上面的
child: Container(
                height: 40,
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(6.0),
                  color: Colors.white,
                ),
