variable reset to initialize value after for each loop
After change value of finalQuizID in if condition in foreach loop, it reset to initialize value in spite of condition is true.
My Code:
class SelectQuizActivity : AppCompatActivity() {
private lateinit var binding: ActivitySelectQuizBinding
private val mFireStore = FirebaseFirestore.getInstance()
private var finalQuizID: String = "NULL"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivitySelectQuizBinding.inflate(layoutInflater)...
