有没有办法在Dart中克隆对象？

class MyClass {
  String name;
  List<String> hobbies;

  MyClass(this.name, this.hobbies);

  MyClass clone() {
    return MyClass(name, hobbies);
  }
}

void main() {
  MyClass original = MyClass('John', ['reading', 'music']);
  MyClass cloned = original.clone();
  
  print(cloned.name); // Output: John
  print(cloned.hobbies); // Output: [reading, music]
}

class MyClass {
  String name;
  List<String> hobbies;

  MyClass(this.name, this.hobbies);

  MyClass clone() {
    List<String> clonedHobbies = List.from(hobbies);
    return MyClass(name, clonedHobbies);
  }
}

void main() {
  MyClass original = MyClass('John', ['reading', 'music']);
  MyClass cloned = original.clone();
  
  cloned.hobbies.add('sports'); // Modify the cloned object

  print(original.hobbies); // Output: [reading, music]
  print(cloned.hobbies); // Output: [reading, music, sports]
}
