How to create a constructor that clones another object in Dart
Here is an example of how you can create a constructor that clones an object in Dart:
class MyClass { int _id; String _name; MyClass(this._id, this._name); // Clone constructor MyClass.clone(MyClass other) : this._id = other._id, this._name = other._name; } void main() { var original = MyClass(1, 'Original'); var clone = MyClass.clone(original); }
In this example, the MyClass
class has a private field _id
and a private field _name
. The main constructor takes two arguments, _id
and _name
, and initializes the corresponding fields.
The MyClass.clone()
constructor is a named constructor that takes another MyClass object as an argument and initializes the new object's fields with the values from the other object. This allows you to create a new object that is a copy of the original object.
To use the clone constructor, you can create an instance of MyClass using the main constructor, and then use the clone constructor to create a new instance of MyClass that is a copy of the original.
