Dart – Anonymous Functions
An anonymous function in Dart is like a named function but they do not have names associated with it. An anonymous function can have zero or more parameters with optional type annotations. An anonymous function consists of self-contained blocks of code and that can be passed around in our code as a function parameter.
- In Dart most of the functions are named functions we can also create nameless function knows as an anonymous function, lambda, or closure.
- In Dart we can assign an anonymous function to constants or variables, later we can access or retrieve the value of closure based on our requirements:
This example defines an anonymous function with an untyped parameter, item. The function, invoked for each item in the list, prints a string that includes the value at the specified index.
