                    controller: _controller,
                    itemCount: 4,
                    itemBuilder: (BuildContext context, int index) {
                      _isValid = false;
                      return [
                          SizedBox.expand(...),
                          SizedBox.expand(...),
                          SizedBox.expand(...),
                          SizedBox.expand(...),
                        ][index];

Answer 1

above one is not worked for me , after the new flutter v2 ( sdk 2.8.1),

NotificationListener<OverscrollIndicatorNotification>(
  onNotification: (overscroll) {
   overscroll.disallowIndicator();
    return true;
   },
child: SingleChildScrollView(

 )
)
