您可以将您RaisedButton.icon的Directionality小部件包装起来：

                    Directionality(
                      textDirection: TextDirection.rtl,
                      child: RaisedButton.icon(
                        onPressed: () {},
                        color: Colors.deepPurple,
                        icon: Icon(
                          Icons.arrow_drop_down,
                          color: Colors.white,
                        ),
                        label: Text(
                          "Category",
                          style: TextStyle(color: Colors.white),
                        ),
                      ),
                    )
