            }
        }
    )
}

Berfungsi mengatur dialog akhir permainan yang muncul ketika game selesai dan memberi tahu pemain skor akhir mereka. Selain itu kode di atas juga mengatur pilihan untuk mpengguna untuk mengulang permainan (Play Again) atau keluar dari aplikasi (Exit).

• WordsData.kt:

package com.example.unscramble.data

const val MAX_NO_OF_WORDS = 10
const val SCORE_INCREASE = 20

// List with all the words for the Game
val allWords: Set<String> =
    setOf(
        "at",

        "birthday",
        "briefcase",
        "motorcycle",
        "cauliflower"
    )

/**
 * Maps words to their lengths. Each word in allWords has a unique length. This is required since
 * the words are randomly picked inside GameViewModel and the selection is unpredictable.
 */
private val wordLengthMap: Map<Int, String> = allWords.associateBy({ it.length }, { it })

internal fun getUnscrambledWord(scrambledWord: String) = wordLengthMap[scrambledWord.length] ?: ""

Berfungsi untuk mendefinisikan konstanta, kumpulan kata yang digunakan dalam permainan, dan fungsi pembantu untuk mencocokkan kata acak ke kata asli.
