Android 我正在创建一个简单的连接四个游戏，我需要一个弹出式窗口当你赢了

这是我的游戏获胜逻辑的代码，我做了它，使它可以水平，垂直和对角.代码可能是错的，但我就是这么做的.我正在试着做一个对话，当你赢了，你赢了，当然，我不知道怎么做，聊天GPT提供的代码总是错误的，或者让我的应用程序崩溃:

 fun checkForWin(board: List<List<Color>>, colorToCheck: Color): Boolean {
    for (boardHeight in 0 until board.size) {
        for (boardWidth in 0 until board[0].size) {
            // Check horizontally
            if (boardWidth + 3 < board[0].size &&
                board[boardHeight][boardWidth] == colorToCheck &&
                board[boardHeight][boardWidth + 1] == colorToCheck &&
                board[boardHeight][boardWidth + 2] == colorToCheck &&
                board[boardHeight][boardWidth + 3] == colorToCheck
            ) {
                return true
            }

            // Check vertically
            if (boardHeight + 3 < board.size &&
                board[boardHeight][boardWidth] == colorToCheck &&
                board[boardHeight + 1][boardWidth] == colorToCheck &&

                return true
            }

            // Check diagonally (from top-left to bottom-right)
