registerForActivityResult.kt

//There are 4 simple steps to follow while replacing the depricated method startActivityForResult(...).


    private val activityResult = this.registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
       when(result.resultCode){
            123 ->{}
           6353 ->{}
       }
    }
    
    private fun navigateToXActivity(activity: AppCompatActivity, itLatLng: LatLng?, address: String) {
        activityResult.launch(XActivity.launch(activity,itLatLng,address)) //XActivity.launch(activity,itLatLng,address) return a intent
    }
 
//returning back to source activity, code will remain the same like -

    val resultIntent = Intent()
        resultIntent.putExtra("NAME OF THE PARAMETER", searchAddressModel);
        setResult(123, resultIntent)
        finish()
