Create a list of objects from Class B to be used as a property in Class A in Dart
I have 8 items in a ListView in my homepage. Clicking one of the items should brings the user to a list of subheadings(different for each item). Each item is an object of a class that has a member variable List<B> I have all the data I need. How do I create List<B>(the subheadings for each item) and associate it with each item. This isn't my code(doesn't compile) but it might explain a little better what I'm looking for...
class A { // The main items in homepage class.
String name;
List<B> bs;
}
class B { // THis class is used for the subheadings
String name;
List<String> subheading;
}
class C{
_aNames= <String>['a','b','c','d']; // these are the main items in my homepage
_subheading= ??????? // <--- What is the best way to present my data
List<B> bs =[ba,bb,bc,bd]; //<---- Im looking for something like this. A list of Bs associated with each item.
}

I think a Map is what you're looking for.
