Reverse list in ListView.builder in Flutter

Question

I wanted to reverse list and I have achieved this by using reverse: true,. It is working, but the list has aligned to the bottom and showing blank space at the top when the list has least items.

 Expanded(child:  ListView.builder(
                shrinkWrap: true,
                reverse: true,
                controller: _scrollController,
                itemCount:order_response.orderDetails.length,
                itemBuilder: (context, position) {return orderListItemTile(width,height,order_response,position);},
              ),)

But when I deleted expanded() widget, when items increase then it overflows by pixel.

 ListView.builder(
            shrinkWrap: true,
            reverse: true,
            controller: _scrollController,
            itemCount:order_response.orderDetails.length,
            itemBuilder: (context, position) {return orderListItemTile(width,height,order_response,position);},
          ),

Apart from reversing the list, another solution could be putting the ListView inside an Align widget with alignment: Alignment.topCenter . Also shrinkWrap: true needed inside ListView.

         Align(
            alignment: Alignment.topCenter,
            child: ListView.builder(
              reverse: true,
              shrinkWrap: true,
              ...
              ...
           )
         )

Reverse your list using:

var reversedList = _response.orderDetails.reversed.toList();
