The FlatButton dosen't take any value and would not return either. What you could do is, pass a void callback that triggers your function that takes button click values as arguments.
Example:
//Define you function that takes click
void _onClick(String value) {
//do something
}
// Make you `FlatButton` like this
FlatButton(
onPressed: () => _onClick('12345678'), // a lambda void callback that calls your click function with value
child: Text('12345678'),
);
Hope that helped!
