body: <p>I've a multi-line text field as below</p>
  <pre><code>val scrollState = rememberScrollState(0)
  
  TextField(
      modifier = Modifier
          .fillMaxWidth()
          .height(75.dp)
          .verticalScroll(scrollState),
      value = caption,
      onValueChange = { onCaptionChanged(it) }
