Flutter text data if coming null?

There is such a code and if the user is logged in as a visitor, it prints null because there is no e-mail information, how can I show it blank?

 Text(
    '$successmail \n\n'  
    style: TextStyle(
    fontSize: 22.0,
    fontStyle: FontStyle.normal,
    fontWeight: FontWeight.w300,
    color: Colors.black,
    letterSpacing: 0,
    ),
    ),

I tried putting things like question marks at the end of the variable but I don't know how to do it exactly.

Try this:

Text(
  '${sucessful ?? "No email"} \n \n'  
  style: TextStyle(
    fontSize: 22.0,
    fontStyle: FontStyle.normal,
    fontWeight: FontWeight.w300,
    color: Colors.black,
    letterSpacing: 0,
  ),
),
