flutter title automatically go to next line

the code below is in wrapped in a row. i need help in getting the text to automatically go to the next line when there’s not enough space. ive been trying to wrap in expanded and stuff but it is not working and throwing me the wrong use of parent widget error. tia

Expanded(
            child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: CrossAxisAlignment.start,
          children:  [
            Text(
              Helpers.getChannelName(channel, context.currentUser!),
              overflow: TextOverflow.visible,
              style: GoogleFonts.lato(
                fontSize: 21,
                
              ),
              maxLines: null,
            ),
            const SizedBox(height: 2),
          ],
        )),

>Solution :

AppBar has limited height, you can have some(2/3) lines like

Text(
  Helpers.getChannelName(channel, context.currentUser!),
  style: GoogleFonts.lato(
    fontSize: 21,
  ),
  maxLines: 3,
  softWrap: true,
),

Also, you can try changing text size by wrapping Text widget with FittedBox or using auto_size_text
