Set RadioGroup selected RadioButton by value of String

Since Kotlin does not support traditional for loop is there a way to select a RadioButton in a RadioGroup if the String x value matched the RadioButton text?

Something like this will work on Java but not in Kotlin

 for(i...radioGroup.childCount){
        int radioButtonID = radioButtonGroup.getCheckedRadioButtonId();
        View radioButton = radioButtonGroup.findViewById(radioButtonID);
        int idx = radioButtonGroup.indexOfChild(radioButton);
    }

Then something like this code to select the correct radio based on String value

if(radioBtn.text.toString.equals("Sample"))
       radioBt.check(R.id.radio1);
    else 
       radioBt.check(R.id.radio2);

rg - your radioGroup

for (rbPosition in 0 until rg.childCount) {
            val rb = rg.getChildAt(rbPosition) as RadioButton
            if (rb.text == yourText) {
                //do stuff for example rb.isChecked = true
            }
        }
