Constructors are special methods that have the same name as a class and are used to initialize an object. Whenever an object is created in a program, it automatically calls the constructor.

Syntax of Constructor:

Types of Constructors in Dart

There are three types of constructors which include:

• Default constructor
• Parameterized constructor
• Named constructor.
  

1. Default constructor:

Default constructors are those constructors that do not have parameters. They are also called not-argument constructors.

2. Parameterized constructor:

Parameterized constructors are those constructors which have parameters through which they take in some variables as arguments. These will help us decide which constructor will be called.

3. Named constructor:

A named constructor is used to create multiple constructors with different names in the same class.

The default constructor takes no arguments, whereas, for the named constructor, a string parameter called is passed.

Finally, the print () statement is used to print the branch on the terminal.
