Flutter textfield expand as user types : <p>I have a textfield and need to have multi-line as below so that the text wraps, however it takes up the space of all the lines that is defined in maxLines.  I want to be able to have it look like 1 line and expand as the text wraps.  Any ideas of how to do this is flutter?</p>

<pre><code>new TextField(
                decoration: const InputDecoration(
                  hintText: 'Reply',
                  labelText: 'Reply:',
                ),
                autofocus: false,
                focusNode: _focusnode,
                maxLines: 1,
                controller: _newreplycontroller,
                keyboardType: TextInputType.text,
              ),
</code></pre>
