I am getting an error in scroll view controller. Here is error:

flutter: 'package:flutter/src/widgets/scroll_controller.dart': Failed assertion: line 149 pos 12: '_positions.isNotEmpty': ScrollController not attached to any scroll views.

I used following code and I hope due to this it is generating:

return ListView(
 controller: _mealScrollController,
 children: <Widget>[
 Container(
 height: screenSize.height * 0.35,
 ),

 WorkWidget(workTime: workTime.morning),
 WorkWidget(workTime: workTime.morning),
 WorkWidget(workTime: workTime.noon),
 WorkWidget(workTime: workTime.evening),
 WorkWidget(workTime: workTime.lateevening),
 WorkWidget(workTime: workTime.night),
 WorkWidget(workTime: workTime.midnight),
 Container(
 child: Center(
 child: RotateWidget(
 child: Icon(
 Icons.refresh,
 size: AppSize.medium,
 ),
 onTap: widget.callBack,
 ),
 ),
 ),
 ],
);
