Flutter RaisedButton设置color 不生效

RaisedButton 是有立体感，有时设置color 不生效，是因为点击禁用了，设置上onPressed就好了

RaisedButton(
                child: Text("点击刷新"),
                color: Colors.lightBlueAccent,
                textColor: Colors.white,
                onPressed: () {},
                padding: EdgeInsets.symmetric(horizontal: 20),
                shape: RoundedRectangleBorder(
                    side: BorderSide(width: 1, color: Colors.white),
                    borderRadius: BorderRadius.all(Radius.circular(10))),
