在使用SliverFixedExtentList展示菜单列表时程序抛出一下异常：

并且在程序的页面上也同样无法正常显示：

相关的代码如下：

SliverFixedExtentList(
          delegate: SliverChildBuilderDelegate((BuildContext context, int index) {
            String title = titles[index];
            return Container(
              alignment: Alignment.centerLeft,
              child: InkWell(
                onTap: () {
                  print("this is the item of " + title);
                },
                child: Column(
                  children: <Widget>[
                    Padding(
                      padding: const EdgeInsets.all(15.0),
                      child: Row(
                        children: <Widget>[
                          Expanded(
                            child: Text(
                              title,
                              style: TextStyle(fontSize: 16.0),
                            ),
                          ),
                          rightArrowIcon
                        ],
                      ),
                    ),
                    Divider(
                      height: 1.0,
                    )
                  ],
                ),
              ),
            );
          }, childCount: titles.length),
          itemExtent: 50.0,
        )
