In what case is it recommended to use immutable objects in Dart?

Immutable objects in Dart are recommended when you need to ensure data safety and predictability of program behavior. This is especially important in multithreaded or reactive applications, where changing the state of an object can lead to errors or debugging difficulties.

Using immutable objects helps to:

• Avoid side effects when passing data.
• Simplify state management in Flutter, for example, when using Provider or Bloc.
• Ensure thread safety without additional synchronization mechanisms.

Example of an immutable class in Dart:

class User {
  final String name;
  final int age;

  const User(this.name, this.age);
}

Here, the fields name and age are declared as final, and the constructor is const, making the object completely immutable after creation.
