# Anonymous Callback Function

* **Callback** is basically a function or a method that we pass as an argument into another function or a method to perform an action.
    

* # Example
    
* ```dart
    void main() {
      // Function that takes a callback function as an argument
      void performOperation(int a, int b, Function(int, int) callback) {
        int result = callback(a, b);
        print('Result of operation: $result');
      }
    
      // Define an anonymous function as the callback
      performOperation(5, 3, (x, y) {
        return x + y; // This is the anonymous function performing addition
      });
    
      performOperation(10, 4, (x, y) {
        return x * y; // This is another anonymous function performing multiplication
      });
    }
    ```
    

* # Output
    
* ```dart
    Result of operation: 8
    Result of operation: 40
    
    Exited.
    ```
