flutter - Objected oriented Dart: access properties in one mixin from another mixin?

I'm using mixins for many of my StatefulWidgets where I declare common properties, and also define methods to initialize those properties.

In the example below, I first wanted to define a method in mixin MCQ, which initializes a few properties that are declared/inherited from the mixin QuizType, but then I realised that that does not work.

So I cannot access properties/methods declared in one mixin, from another mixin, when using both mixins on the same class. Is there a way I can achieve this functionality using the implements keyword on (abstract) classes? I obviously can't use the extend keyword anymore for other things, as it's already needed for the State.

class _MultipleChoiceSentencesState extends State<MultipleChoiceSentences> with QuizType, MCQ {
