合并Dart中的两个对象列表

class Person {
  final String name;
  final int age;

  Person(this.name, this.age);
}

void main() {
  List<Person> list1 = [Person('Alice', 30), Person('Bob', 25)];
  List<Person> list2 = [Person('Charlie', 35), Person('David', 40)];

  // 方法1: 使用加号操作符
  List<Person> combinedList1 = list1 + list2;
  print(combinedList1);

  // 方法2: 使用addAll方法
  List<Person> combinedList2 = [...list1];
  combinedList2.addAll(list2);
  print(combinedList2);

  // 方法3: 使用spread operator
  List<Person> combinedList3 = [...list1, ...list2];
  print(combinedList3);
}

List<Person> uniqueCombinedList = [...list1.toSet(), ...list2.toSet()].toList();

List<dynamic> mixedList = [...list1, ...list2.map((e) => e as dynamic)];
