Why is the text and the radio on opposite side? Are you using rtl layout? Or, have you changed the layout from (Radio - Conteent) to (Content - Radio)?

I really don't know why. I will check whats happens and make a pr if necessary.
Nice catch

@ExpertKiD I discovered why this happens. In example code is set controlAffinity: ControlAffinity.trailing so the radio button is move to right side
