如何删除颤振列表？

Question

我在重新启动游戏时搜索以删除位置列表

这是我的列表

   List<Positioned> snakePiecesWithNewPoints = List();

    if (score ==0){
          final latestPoint = Positioned(
            child: newSnakePointInGame,
            left: newPointPosition.x * 15.5,
            top: newPointPosition.y * 15.5,
          );
      snakePiecesWithNewPoints.add(latestPoint);
    };


        if (score ==1){


          final latestPoint1 = Positioned(
            child: newSnakeVomiInGame,
            left: newPointPosition2.x * 15.5,
            top: newPointPosition2.y * 15.5,
          );
          snakePiecesWithNewPoints.add(latestPoint1);

        };

我尝试仅删除LatestPoint1而不是LatestPoint
