Helo have face a slight issue which is eating up my head. i have such json as shown above. but if you look closely the first 3 cars are duplicates and the last 2 are aslo the same i want to have a way that i will have no duplicates such that am going to have a list with only the two cars being unique. I want the data to be displaayed on my app to be having a length o two cars
take your list and filter using where
final existing = Set<String>();
bookings.where((person) => existing.add(person.car.id))
.toList();
print('unique $unique');
// unique [Instance of 'Bookings', Instance of 'Bookings']
