helper for shared prefs - kotlin version - Refactoring step 4

PreferenceHelper.kt

    inline fun SharedPreferences.edit(operation: (SharedPreferences.Editor) -> Unit) {
        val editor = this.edit()
        operation(editor)
        editor.apply()
    }

     fun SharedPreferences.setValue(key: String, value: Any?) {
        when (value) {
            is String? -> edit({ it.putString(key, value) })
            is Int -> edit({ it.putInt(key, value) })
            is Boolean -> edit({ it.putBoolean(key, value) })
            is Float -> edit({ it.putFloat(key, value) })
            is Long -> edit({ it.putLong(key, value) })
            else -> throw UnsupportedOperationException("Not yet implemented")
        }
    }

val prefs = PreferenceHelper.customPrefs(this, Constants.SHERED_PREFERENCE_USER) prefs[Constants.USER_UID] = "UserId"

I haven't been actively working on Android. If you can make the necessary changes, it will be helpful. Thanks.
