我需要将 GridView 的所有项目与水平线和垂直线分开。谢谢

         GridView(
                   shrinkWrap:true,
                   gridDelegate: SliverGridDelegateWithFixedCrossAxisCount( 
                   childAspectRatio: 1.0,
                   mainAxisSpacing: 2.0,      
                   crossAxisSpacing: 2.0,
                   crossAxisCount: 3),
                   children: <Widget>[
                     GestureDetector(
                       onTap: () {
                         //_settingModalBottomSheet(context);
                       },
                       child: itemWidgetDialog()
                     ),
                     for (int i=0; i<10;i++) ...[
                      itemWidgetDialog()
                     ]
                   ],

                 )),
