All you have to do is "concatenate" strings.

String mytext = 'starting text';

TextButton(
  onPressed: ()  {
     setState(() {
     mytext = mytext + imageList[anu1].wrongSpell1;
    });

  },
   child: Text(imageList[anu1].wrongSpell1),
  )

//// here is where you would show your text:
Text(mytext)

All you need to do is:

String myname = 'ottoman';
setState(() {
     myname = myname + imageList[anu1].wrongSpell1;
});
