is it setState issue or is it correct ?

The below code also works very well. See the last line where setState does not have anything inside it, but everything is outside it. Still everything works.

void checkAnswer(bool userPickerAnswer) {
    bool correctAnswer = quizBrain.getQuestionAnswer();
    if (userPickerAnswer == correctAnswer) {
      scoreKeeper.add(Icon(
        Icons.check,
        color: Colors.green,
      ));
      print('user got it right');
    } else {
      scoreKeeper.add(Icon(
        Icons.close,
        color: Colors.red,
      ));
      print('user got it wrong');
    }
    quizBrain.nextQuestion();
    setState(() {});
  }

Same here, the SetState doesn't work for me ... i don't know why

Expanded( child: Padding( padding: EdgeInsets.all(15.0), child: FlatButton( textColor: Colors.white, color: Colors.green, child: Text( 'True', style: TextStyle( color: Colors.white, fontSize: 20.0, ), ), onPressed: () { //The user picked true. setState(() { scoreKeeper.add( new Icon( Icons.check, color: Colors.green, ), ); }); }, ), ), ),
