You can simply use the map method to achieve this:

List<String> myCategory = mycategories.map((e) => e.nameCategory).toList();
print(myCategory); // Prints [Salary, Interest, Award]

this will give you what you need

List<Categories> s1 = [];
List<String> ss = [];
result!.map((e) {
  ss.add(e.nameCategory);
});
