Pass a function with parameters to a VoidCallback

Question

Is it possible to pass a Function with parameters to a VoidCallback?

for example something like this:

class MyClass {
  void doSomething(int i){

  }

           


        

Answer 1

1) Create typedef first in any constant class:

typedef StringVoidFunc = void Function(String);

2) Pass from calling function class one

showAlertDialog(doSomething);

3) Call back handle Function

void doSomething(String i){
Navigator.pop(context);
setState(() {

});

}

4) From where you want to fire call back from Class Two

    showAlertDialog(StringVoidFunc callback) {
     callback("delete");
}
