嵌套在CustomScrollView使用抛出异常

[CrazyCoderShi]

RT: 我在CustomScrollView中的嵌套使用，在自动滚动的过程中会抛出如下异常:

flutter: Another exception was thrown: ScrollController not attached to any scroll views.

我在listview里面嵌套也是这个错

[MeFelixWang]

不知道你的实际情况，说一下我的解决方案：如果是从网络请求的数据，请加上if...else...判断，在数据回来之前return一个Container @CrazyCoderShi @xuwankang

Widget _widgetPlanList() {
final controller = new SwiperController();
return Swiper(
controller: controller,
// index: _swiperIndex,
itemBuilder: _swiperBuilder,
itemCount: menuList.length,
itemWidth: ScreenUtil().setHeight(750),
itemHeight: ScreenUtil().setHeight(1040),
scrollDirection: Axis.horizontal,
onTap: (index) {
print('onTap点击了第$index个');
},
onIndexChanged: (int i) {
setState(() {
_activeIndex = i;
});
print('onIndexChanged点击了第$i个');
});
}
没有注释index:_swiperIndex前，我也是报一样的错误，注释掉就好了

跳转到指定索引：controller.move(index);

[CrazyCoderShi]

@zhaowenxin 我压根没有使用这个属性...

遇到了这个问题，求结局方案

[CrazyCoderShi]

@MayIGetKepler 解决方案就是放弃这个repo，作者根本不关心issue

I found the solution!!
Your Swiper must be wrap with StreamBuilder or something that rebuild more than once Swiper.
In my case,
StreamBuilder( stream: slides, initialData: [], builder: (context, AsyncSnapshot snap) { List slideList = snap.data.toList(); return slideList.isNotEmpty ? Swiper( itemBuilder: (BuildContext context, int index) { return Image.network( slideList[index]['image'], fit: BoxFit.fill, ); },
Check the slideList not empty.
