How to set the dynamic position of swiper coming from api

[ankitkumar333111]

It shows the below error-

Unhandled Exception: 'package:flutter/src/widgets/scroll_controller.dart': Failed assertion: line 110 pos 12: '_positions.isNotEmpty': ScrollController not attached to any scroll views.

-----------my code-------

Swiper(
//outer: true,
fade:0.0,
viewportFraction: 0.4,
scale: 0.8,
index: widget.temp-totalTempCount,
itemBuilder: (c, i) {
return Center(child: Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text((setTemperature(i)).toString(), style: TextStyle(fontSize: 48.0, color: AppTheme.whiteTextColor)),
Text("\u00B0"+ "C", style: TextStyle(fontSize: 32.0, color: AppTheme.whiteTextColor)),
]));
},
onIndexChanged: (int index) {
setState(() {
currentIndex = index;
});
widget.tempChangeCallback(totalTempCount + index);
},
itemCount: 15)

The Callback expects a return. Do it like this:

Swiper(
            itemBuilder: (BuildContext context, int index) {
              return slides[index];
            },
            itemCount: slides.length,
            pagination: new SwiperPagination(margin: EdgeInsets.all(15)),
            control: new SwiperControl(),
            layout: SwiperLayout.DEFAULT,
            onIndexChanged: (int index) {
              return setState(() => currentSlide = index);
            }),

Map your array this way;

data[index]["..."]["..."]
