                    ? Icon(Icons.check_circle)
                    : Icon(
                        Icons.check_circle_outline,
                        color: Colors.grey,
                      )),
                color: Colors.lightBlueAccent,
                iconSize: 35.0,
                splashColor: Colors.tealAccent,
                onPressed: _toggleFavorite,
              ),
            ),
      Stack(
       children: <Widget>[
         Padding(
           padding: const EdgeInsets.only(bottom:10.0),
           child: Divider(
             height: 40.0,
           ),
         ),
         Center(
           child: IconButton(
             icon: (_isFavorited
                 ? Icon(Icons.cancel)
                 : Icon(
               Icons.cancel,
               color: Colors.grey,
             )),
             color: Colors.lightBlueAccent,
             iconSize: 35.0,
             splashColor: Colors.tealAccent,
             onPressed: _resetSetData,
           ),
         ),

       ],
      ),

      ListTile(

              title: Center(
                child: new Text(
                  "10 reps",
                  style: TextStyle(
                    fontSize: 18.0,
                    color: Colors.black,
                    decoration: TextDecoration.none,
                    decorationStyle: TextDecorationStyle.double,
                    fontFamily: 'Raleway-Medium',
                  ),
                ),
              ),
            ),
    ],
  );
}

void _toggleFavorite() {
   setState(() {
    if (_isFavorited) {
     _isFavorited = false;
   } else {
     _isFavorited = true;
  }
});
}

void _resetSetData() {
  setState(() {
    if (_isFavorited) {
    _isFavorited = false;
  } else {
    _isFavorited = true;
  }
});
 }

实现此用户界面的最佳方法是什么？

使用容器包装列表图块，并使用bool维护图块的状态，以便您可以更改列表图块的颜色。谢谢
