Non-nullable instance field 'questionText' must be initialized. Try adding an initializer expression, or add a field initializer in this constructor, or mark it 'late'.

I have this error in the question. dart file. How can I correct it?

`class Question { late String questionText; late bool questionAnswer;

Question({required String q, required bool a}) { questionText = q; questionAnswer = a; } } ` one of the possoble solution

[tlaw22]

class Question { final String questionText; final bool questionAnswer;

Question({ required this.questionText, required this.questionAnswer, }); }
