In short: void means nothing and dynamic means anything.

This means, a void function can't return anything. You can try and you will get an error in your IDE. A dynamic function can return anything, "void " included. Try it by returning a string or a double or a list, everything is allowed.

However, usually a function should not return dynamic. It should serve a single purpose and if it returns something (or nothing), the return type should be defined.

In your example, I'd use void as your function does not return anything.
