title: Multi-line Textfield in flutter
body: <p>It may sound easy but How can we do a multi-line editable textfield in flutter? TextField works only with a single line. </p>
  
  <p><strong>Edit:</strong> some precisions because seems like it's not clear.
  While you can set multiline to virtually wrap the text content, it's still not multiline. It's a single line displayed into multiple lines.
  If you want to do something like this then you can't. Because you don't have access to <code>ENTER</code> button. And no enter button means no multiline.</p>
