Dart: Redirecting Constructor
Published
•1 min read
Sometimes a constructor's only purpose is to redirect to another constructor in the same class.
In simple words, inside in class when a constructor calls another constructor within the same class, we refer to this process as a Redirecting Constructor.
A redirecting constructor's body is empty with the constructor call appearing after a colon (:).
class Display{
Display(this.x, this.y);//parameterized constructor
Display.re_const(): this(2, 4);//named constructor
Display.named() : this(10, 20);is a redirecting constructor namednamed.It doesn't take any parameters.
It redirects the construction process to the primary constructor by using constructor delegation
this(10, 20).When an object is created using this constructor, it immediately redirects to the primary constructor with values
10and20forxandy, respectively.
