void _onIndexChanged(int index) {
setState(() {
_activeIndex = index;
});

对于itemCount属性的使用，出现过问题吗？我这里无法给itemCount属性动态赋值，只能写成固定的数字。
Swiper( itemCount: bannerList.length, autoplay: true, itemBuilder: (BuildContext context, int index) { if (bannerList.length == 0) { return null; } return Image.network( bannerList[index].icon, fit: BoxFit.cover, ); }, pagination: SwiperPagination( builder: DotSwiperPaginationBuilder(activeColor: Colors.red), ), // control: SwiperControl(), onTap: (int index) { print('点击了图片：' + index.toString()); }, )
