我是颤振的初学者,我无法在材质小部件上插入圆形边框。我已经插入了适当的内容borderRadius: new BorderRadius.circular(6.0),,但我看不出我做错了:
我的代码:
Widget _buildCategoryItem(index) {
return new GestureDetector(
onTap: () {
onTabCategory(index);
},
child: new Center(
child: new Container(
margin: new EdgeInsets.only(left: 10.0),
child: new Material(
elevation: 2.0,
borderRadius: new BorderRadius.circular(6.0),
child: new Container(
padding: new EdgeInsets.only(
left: 12.0, top: 7.0, bottom: 7.0, right: 12.0),
color: _category_selected == index
? Colors.orange[800]
: Colors.orange[500],
child: new Text(
_categorys[index],
style: new TextStyle(color: Colors.white),
),
),
),
),
),
);

类别标签的格式为方形,但我想将其边框设置为圆形:
