All chips need to have the android:checkable="true" property for the trigger to exist on them.

In adittion to setting the initial check of any chip (without giving a tap), the order of execution must be first the creation of the listener with chipGroup.setOnCheckedChangeListener() and then chip.isChecked = true.

So you could handle the checkable property from the xml and isChecked dynamically.

.xml

.kt

binding.chipGroup.setOnCheckedChangeListener { chipGroup, i -> 

}
binding.firstChip.isChecked = true   //default
