只需使用 mainAxisAlignment 将一列放在中心： MainAxisAlignment.center

 Row( mainAxisAlignment: MainAxisAlignment.spaceBetween, children: [
              Container(
                height: double.infinity,
                width: 100,
                color: Colors.red,
              ), Column(
                mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Container( height: 100, width: 100, color: Colors.redAccent, ),
                Container( height: 100, width: 100, color: Colors.white, ),
              ],
            ), Container( height: double.infinity, width: 100, color: Colors.blue, ), ])
