Dart Anonymous Functions: Callback Functions

Basically, in Dart the Callback function is like normal function, but it is passed as arguments to another function.

You are getting the same of instructions repeatedly at multiple places, you can use the callback function at one place.

Here's a simple example of using a callback function in Dart:

• performTask is a function that takes a callback function as an argument. It performs some task (here simulated by a loop) and then calls the callback function once the task is complete.

• myCallback is the callback function that simply prints "Task completed!".

• In main(), we call performTask and pass myCallback as the callback function.

This demonstrates how callback functions work in Dart, where a function can be passed as an argument to another function and then called back later when needed. Callback functions are essential for handling asynchronous tasks, event handling, and more in Dart programming.
