Why would you pass a function as a parameter?

Passing a function as parameter to another function is actually one of the most useful constructs in programming with a variety of applications. One example is that the function parameter can change the behaviour of the function into something that is not determined at compile time .

You can do it like this, Future<String> _myFunction(Future<Response> Function() function) { … }

You can do it like this, Future<String> _myFunction(Future<Response> Function() function) { … }

We cannot pass the function as an argument to another function . But we can pass the reference of a function as a parameter by using a function pointer. This process is known as call by reference as the function parameter is passed as a pointer that holds the address of arguments.

Curly brackets {} are used to specify optional, named parameters in Dart . Named parameters are referenced by name, which means that they can be used during the function invocation in an order different from the function declaration.
