颤振|将 expandCenterPage 设置为 true 时出现 Carousel Slider 错误，

Question

CarouselSlider(
                              carouselController: CarouselController(),
                              items: <Widget>[
                                Container(height:100),
                                Container(height:100),
                                Container(height:100),
                              ],
                              options: CarouselOptions(
                                  //when this line is commented the error vanishes
                                  enlargeCenterPage: true,
                                  height: 180.0,
                                  enlargeStrategy: CenterPageEnlargeStrategy.scale,

                                  enableInfiniteScroll: true,
                                  autoPlayAnimationDuration:
