[TextInput]How to get content height when TextInput has a defaultValue

I want to write a auto grow text input, i know onChange will pass contentSize in event.nativeEvent

<TextInput
  onChange={event => {
      event.nativeEvent.contentSize.height
  }}
/>

but if input has a defaultValue, how to get the content height?

sorry for my english…

Actually, onLayout is not triggered for TextInput. Doing more testing, but first findings are negative…
