Hi I'm new to kotlin and I'm working on the words dictionary app I accidentally deleted a line of code but managed to put it back in and now for some reason it's not working. The error is expecting member declaration. I'm guessing it's linked to line 118 of the code expecting top level declaration, it's just a curly bracket. PLease help

/**
 * Adapter for the [RecyclerView] in [DetailActivity].
 */
class WordAdapter(private val letterId: String, context: Context) :
    RecyclerView.Adapter<WordAdapter.WordViewHolder>() {

    private val filteredWords: List<String>

    init {
        // Retrieve the list of words from res/values/arrays.xml
        val words = context.resources.getStringArray(R.array.words).toList()

        filteredWords = words
            // Returns items in a collection if the conditional clause is true,
            // in this case if an item starts with the given letter,
            // ignoring UPPERCASE or lowercase.
            .filter { it.startsWith(letterId, ignoreCase = true) }
            // Returns a collection that it has shuffled in place
            .shuffled()
            // Returns the first n items as a [List]
            .take(5)
            // Returns a sorted version of that [List]
            .sorted()
