我正在开发一些棋盘游戏

验证码：

static List<Ball> calculateAllMoveCordsForHardMove(int wichBoard) {
    final List<Ball> moveList =
       navigatorKey.currentContext!.read(gameStatusProvider).moves;

    print(
        'Cord(${moveList[0].cord?.x.toString()}, ${moveList[0].cord?.y.toString()})');

    for (int i = 0; i < moveList.length; i++) {
      final boardNumber = moveList[i].wichBoard ?? 0;
      if (boardNumber == wichBoard) {
        final cord = moveList[i].cord ?? Cord(0, 0);

        final newCord = nextCord(cord, boardNumber);//just returuns a cord
        moveList[i].cord = newCord;
      }
    }

    final moves2 =
        navigatorKey.currentContext!.read(gameStatusProvider).moves;

    print(
        'Cord(${moves2[0].cord?.x.toString()}, ${moves2[0].cord?.y.toString()})');

    return moves;
  }

输出：

flutter: Cord(0, 2)
flutter: Cord(0, 0)

read返回一个可变引用
当我更改moveList时，也会更改提供程序的值
我不想更改提供程序的值，仅此而已。
谢谢。
