do someone have any idea what I did wrong?

Both ways looks ok, I have a couple of suggestions that you could try:

1. try to write as normal function

@BindingAdapter("errorText")
fun setErrorText(view: TextInputLayout, errorText: String?) {
   view.error = errorText
}

2. try to specify setter parameter type:

@set:BindingAdapter("errorText")
var TextInputLayout.errorText: String?
   get() = error.toString()
   set(value: String?) {
       error = value
   }

I've solve it

in the xml I was trying to set it as app:errorText or android:errorText

[alle.iacob]

but it was enough errorText

[nikolay]

wait, don’t get, but it should work with app as well

I've tried both your examples

[alle.iacob]

you can see code that I've copied to the chat

[alle.iacob]

but it didn't worked

[nikolay]

could you, please, show the layout where you are using it? just curious.

[alle.iacob]

full file?

[alle.iacob]

bottom_fragment.xml

bottom_fragment.xml

[alle.iacob]

on pin_edit_text_layout

[alle.iacob]

but temporarily I've removed it

and the view model is an AndroidViewModel
