如何删除dart类列表中具有相同参数的元素？

class MyClass {
  int id;
  String name;

  MyClass(this.id, this.name);
}

List<MyClass> myList = [
  MyClass(1, 'A'),
  MyClass(2, 'B'),
  MyClass(3, 'C'),
  MyClass(2, 'B'),
  MyClass(4, 'D'),
];

myList = myList.where((element) => myList.where((e) => e.id == element.id && e.name == element.name).length == 1).toList();

myList.forEach((element) {
  print('id: ${element.id}, name: ${element.name}');
});

class MyClass {
  int id;
  String name;

  MyClass(this.id, this.name);
}

void main() {
  List<MyClass> myList = [
    MyClass(1, 'A'),
    MyClass(2, 'B'),
    MyClass(3, 'C'),
    MyClass(2, 'B'),
    MyClass(4, 'D'),
  ];

  myList = myList.where((element) => myList.where((e) => e.id == element.id && e.name == element.name).length == 1).toList();

  myList.forEach((element) {
    print('id: ${element.id}, name: ${element.name}');
  });
}
