How to access children components of a view inside a LinearLayout that has been added as view inflated with viewBinding?

Question

I want to know how to access innerElement inside a custom view that was added inside a LinearLayout.

Working inside a Fragment I create a view like this:

val view = ConstrainLayout1Binding.inflate(layoutInflater)

then add some data to ConstrainLayout1 components like view.innerElement = something

then add this view to a LinearLayaout inside a cardView

binding.MyMaterialCard.MyLinearLayout.addView(view.root)

Now in another part of the fragment I need to iterate MyLienarLayout and accesss ConstrainLayout1 elements:

When I do

binding.MyMaterialCard.MyLinearLayout.children.forEachIndexed { index, view-> as here I have a view I cannot access elements inside ConstrainLayout1

 view.innerElement   not posible

}

How should I iterate the LinearLayout to have access again to the innerElements?
