To display on UI, currently you can use EasyScrollToIndex.

Example:

• vertical

          final ScrollToIndexController _controller = ScrollToIndexController();

          EasyScrollToIndex(
              controller: _controller,            // ScrollToIndexController
              itemCount: 100,                     // itemCount
              itemWidth: 50,
              itemHeight: 100,
              itemBuilder: (BuildContext context, int index) {
               return Container(
                 width: 50,
                 height: 100,
                  decoration: BoxDecoration(
                    border: Border.all(color: Colors.black,width: 1),
                  ),
                  child: Center(child: Text('item '+ index.toString())),
                );
              },
            ),

• horizontal

            final ScrollToIndexController _controller = ScrollToIndexController();
            
            EasyScrollToIndex(
              controller: _controller,            // ScrollToIndexController
              scrollDirection: Axis.horizontal,   // default Axis.vertical
              itemCount: 100,                     // itemCount
              itemWidth: 50,
              itemHeight: 100,
              itemBuilder: (BuildContext context, int index) {
               return Container(
                 width: 50,
                 height: 100,
                  decoration: BoxDecoration(

                  ),
                  child: Center(child: Text('item '+ index.toString())),
                );
