Class member fields not initialized when constructor is called in flutter-CodePudding

I am new to flutter. As a learning project i am building a quiz app. I am using Flutter riverpod for state management. Currently, there are three layers (model, repository, view) in my project. quiz.model.dart is connected to quiz.repository.dart and quiz.repository.dart is connected to home.view.dart. Whenever i call quiz repository it gives me error

LateError (LateInitializationError: Field 'question' has not been initialized.)

The link to the project repository is here. I have also created a new branch error_fix for this purpose. Kindly propose your changes in that branch. Any help will be appreciated as i have already spend a large amount of time on this. Thank You!

You haven't defined the 'this' keyword in the 'Question' class constructor. You should change the code as in the examples below.

change

  Question({
    required category,
    required type,
    required difficulty,
    required question,
    required correctAnswer,
    required answers,
  });

  Question({
    required this.category,
    required this.type,
    required this.difficulty,
    required this.question,
    required this.correctAnswer,
    required this.answers,
  });
