This code was written before inside oncreate it was working fine but when i shifted it down in order to create a function this "it" is showing these errors, i had checked there is no variable like "it"

this is the code

  if (manager.getInt("limitOfBox") > 0) {
        Bloom.with(this)
            .setParticleRadius(5f)
            .setEffector(
                BloomEffector.Builder()
                    .setDuration(1500)
                    .setAnchor(
                        (it.width / 2).toFloat(),
                        (it.height / 2).toFloat()
                    )
                    .build()
            )
            .boom(it)

and these are the errors, "it" is turned red

so please tell me what to write instead of "it" , so that it don’t throw errors.

this is the old code which was working perfectly :-

class LuckyBoxActivity : AppCompatActivity() {

lateinit var binding: ActivityLuckyBoxBinding
lateinit var db: FirebaseFirestore
lateinit var myRepo: MyRepo
lateinit var manager: PrefManager
val activity = this

@SuppressLint("SetTextI18n")
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    binding = ActivityLuckyBoxBinding.inflate(layoutInflater)
    setContentView(binding.root)
    showProgress()

    var winningCoins = 0
    var limit = 0

    db = FirebaseFirestore.getInstance()
    myRepo = MyRepo(this)
    manager = PrefManager(this)

    loadBanner()




    db.collection("Earning").document("box")
        .addSnapshotListener { value, error ->
            if (error == null) {
                val data = value?.toObject(WatchVideoModel::class.java)
                winningCoins = data?.winningCoins.toString().toInt()
                limit = data?.limit.toString().toInt()

                Log.e("luck Box", "onCreate: $winningCoins")
                Log.e("luck Box", "onCreate: $limit")

                if (manager.getInt("limitOfBox") == 102) {
                    binding.limit.text = "$limit"
                    manager.setInt("limitOfBox", limit)
                } else {
                    binding.limit.text = manager.getInt("limitOfBox").toString()
                }
                dismissProgress()
            }
        }



    binding.giftImg.setOnClickListener {



        val winningAmount = (0..winningCoins).random()

        if (manager.getInt("limitOfBox") > 0) {
            Bloom.with(this)
                .setParticleRadius(5f)
                .setEffector(
                    BloomEffector.Builder()
                        .setDuration(1500)
                        .setAnchor(
                            (it.width / 2).toFloat(),
                            (it.height / 2).toFloat()
                        )
                        .build()
                )
                .boom(it)

            Handler(Looper.getMainLooper()).postDelayed(Runnable {
                binding.giftImg.visibility = View.INVISIBLE
            }, 1000)
            Handler(Looper.getMainLooper()).postDelayed(Runnable {

                manager.setInt("limitOfBox", manager.getInt("limitOfBox") - 1)
                binding.limit.text = manager.getInt("limitOfBox").toString()

                binding.resultText.visibility = View.VISIBLE

                if (winningAmount == 0) {
                    binding.resultText.text =
                        "Oops !! better luck next time..."
                } else {
                    binding.resultText.text = "$winningAmount Coins"
                    myRepo.addCoins(winningAmount.toString().toDouble())
                }
            }, 1500)

        } else {
            showToast("Daily Limit Over")
        }
    }
}

fun loadBanner() {
    val view = BannerView(this@LuckyBoxActivity, constants.banner, UnityBannerSize(320, 50))
    view.load()
    binding.bannerAd.addView(view)
}
companion object {
    private const val TAG = "LuckyBoxActivity"

  1. it here stands for the view that you want this Bloom Effect on.

    Refer to the example given by the library itself.

     Bloom.with('activity')
     .setParticleRadius(5)
     .setEffector(new BloomEffector.Builder()
         .setDuration(800)
         .setAnchor(view.getWidth() / 2, view.getHeight() / 2)
         .build())
     .boom(view);
    

    here view is the item in which the effect is to be created.

  2. Where you moved your code from most likely was inside a scope function. We can’t tell you what it is without you showing us the code in onCreate where you got it from.

    A very common scope function is the scope funtion let. If you do for example

    val a = "test"
    a.let {
        print(it)
    }
    

    then it refers to the variable a. Maybe something like that was used there.
