[移动开发]Flutter GestureDetector增大点击区域

如点击一个文字加图标，外面是Row,发现点击区域很小，代码如下：

    GestureDetector(
                      onTap: () async {
                        Routers.push(Routers.regularListPage, context,
                            callBack: (value) => homeModel.refreshData());
                      },
                      child: Row(
                          mainAxisAlignment: MainAxisAlignment.end,
                          children: <Widget>[
                            Text(
                              S().string_all,
                              style: TextStyle(
                                color: colorA4A4A4,
                                fontSize: 12,
                                decoration: TextDecoration.none,
                              ),
                            ),
                            SizedBox(width: 2),
                            Container(
                                margin: EdgeInsets.only(top: 1.6),
                                child: Icon(Icons.arrow_forward_ios,
                                    size: 10.0, color: colorA4A4A4))
                          ])),

修改方法外面包裹Container 然后并且必须设置背景色， 如果不设置背景色，点击区域仅仅是里面图片和文字的很小的范围，

        GestureDetector(
                    onTap: () async {
                      Routers.push(Routers.regularListPage, context,
                          callBack: (value) => homeModel.refreshData());
                    },
                    child: Container(
                        color: appWhite, //包裹Container 然后并且设置背景色
                        child: Row(
                            mainAxisAlignment: MainAxisAlignment.end,
                            children: <Widget>[
                              Text(
                                S().string_all,
                                style: TextStyle(
                                  color: colorA4A4A4,
                                  fontSize: 12,
                                  decoration: TextDecoration.none,
                                ),
                              ),
                              SizedBox(width: 2),
                              Container(
                                  margin: EdgeInsets.only(top: 1.6),
                                  child: Icon(Icons.arrow_forward_ios,
                                      size: 10.0, color: colorA4A4A4))
                            ])),
                  ),
