You can achieve by spread operator which unfold the Iterable<Widget> as follows:

RichText(
  text: TextSpan(
    text: 'Items\n',
    children: <TextSpan>[
      for(var i = 0; i< items.length; i++)
        ...[
          TextSpan( text: 'Item ${i.toString()}: '),
          TextSpan( text: '${items[i]} \n',),
        ],
    ],
  ),
)

You can check it out in DartPad also.
