Adding and Removing pages in Swiper about flutter_swiper HOT 9 OPEN

Hey, I was able to solve this by dispose/recreate the wrapper widget of the swiper() by giving a UniqueKey each time I was going to pass data to the swiper.

the state is maintained in the parent widget, sample code:

MySwiperWrapper(key: UniqueKey(), images: images, ......)

class MySwiperWrapper extends StatefulWidget { ....... MySwiperWrapper ({ @required Key key, @required this.images, }) : super(key: key); ..... }

NOTE: it's not an efficient solution, but it works

@zeromaro, hope this helps you

Hey, was this issue fixed? As I face exactly same thing. I receive an error
ScrollController not attached to any scroll views. 'package:flutter/src/widgets/scroll_controller.dart': Failed assertion: line 110 pos 12: '_positions.isNotEmpty'
After I remove an item from Swiper.

Cheers

Same problem here ! You can avoid it by saving a reference to the SwiperController and call its previous method just before deleting the widget (Future.delayed() may come handy...)

Actually, the problem occurs when deleting the first element as well, and I have no solution for that yet.

嵌套在CustomScrollView使用抛出异常,进行swiper count 判断，如果数量为空则不显示，数量不为空在显示 if (null == _swipers || _swipers.isEmpty) ? SizedBox() : _swiper() ;

this fixed my issue, as well. thanks!

I am using the SwipperController with the Swiper object and calling the move function, which was causing the "ScrollController not attached to any scroll views" exception. Adding a unique key to my Swiper object did not resolve the exception. What finally fixed the problem for me was setting the animation field to false when move is called: swiperController.move(provider.getCurrentActiveIndex(), animation: false);
