When we define a constructor in Dart, we define the initialization followed by any code that we want to want run.

class User {
  final int id;
  final String name;
  
  User(this.id, this.name); 
}
final String uniqueId;
User(this.id, this.name) : uniqueId = '$id$name';
User(this.id, this.name) : uniqueId = id.toString() + name;
print(100.toString());
print(43.isEven)
var user = User(42, 'Ray');
print(user.uniqueId);
User(this.id, this.name) : uniqueId = id.toString() + name {
  print(uniqueId);
}
