In this article, we are going to learn about the Callable classes in Dart.
Dart facilitates us to call the class instances like a function.
To allow an instance of your Dart class to be called like a function, implement the call() method from the Dart official. Please check the below code:
call()
Output: 16
In the above example, the ClassAsFunction class defines a call() function that takes two integers and returns the product of them.
ClassAsFunction
Note: Dart doesn’t allow us to create multiple call() functions for a class and if you do that, Dart raises the compilation error. Please check the below code:
error The name ‘call’ is already defined.
Thanks for reading.
Happy Coding 🙂
