flutter multiline text field

new TextField(
  keyboardType: TextInputType.multiline,
  maxLines: whatever,
)

Text(
     "TOP ADDED",
     textAlign: TextAlign.justify,
     overflow: TextOverflow.ellipsis,
     style: TextStyle(fontSize: 18.0),
     maxLines: 2,)

// All that is required for multi-line text, is that your Text() widgets' 
// width is limited by a parent widget. For example:

SizedBox(
    width: 150,
    child: Text(
    "This text is very very very very very very very very very very very very very very very very very very very very very very very very very long",
    ),
),
