What is the super Keyword in Dart ?

• The super keyword in Dart is used to refer to the object of the immediate parent class of the current child class.

• The super keyword is also used to call the parent class’s methods, constructor, and properties in the child class.

Benefits of the super keyword

• When both the parent and the child have members with the same name, super can be used to access the data members of the parent class.

• super can keep the parent method from being overridden.

• super can call the parent class’s parameterized constructor.

Syntax

•   // To access parent class variables
    super.variable_name;
  
    // To access parent class method
    super.method_name();
  

Example

•   class me {
      men() {
        print('Hiii');
      }
    }
  
    class You extends me {
      void one() {
        super.men();
      }
    }
  
    void main() {
      var one = You();
  
      one.men();
    }
  

Output

Hiii

Exited.
