various-ways-to-invoke-functions-in-dart

You mix positional and named arguments in Dart functions by placing positional arguments first and appending named arguments, which enables flexible argument reordering and concise invocation patterns.

The .call operator in Dart allows you to invoke a function directly using its function reference. You explicitly call the .call method on the object to execute the function block.

To dynamically invoke a Dart function at runtime, use the Function.apply method. This approach passes arguments as a list and handles dynamic invocation, but be aware of potential performance implications.

Callable objects in Dart are classes that implement the call method, allowing instances to be invoked like standard functions. They are needed when runtime adaptability and flexible function calls are required.

Yes, there are performance implications when using Function.apply for dynamic invocation in Dart. While it provides runtime adaptability for flexible function calls, explicit static invocation generally performs better.
