Why does this code work:

addNumbers(num1, num2) {
print(num1   num2);
}

void main() {
addNumbers(1, 2);
}

But this code doesn't work:

addNumbers(num1, num2) {
  num1   num2;
}

void main() {
 int result = addNumbers(1, 2);
 print('$result');
}

How to make it work?

Sorry, I'm very new in programming and i don't know if it's possible.

void main(){
    var list =["ashu","lakhan","ankit","arv","vijay"];
    print("Iterating the List Element");
    list.add('mohan');
    for(var a in list){  
        print('${list.indexOf(a)}=$a');
    }
}

using await in async, look below for sample

void main() async{   

int result = await addNumbers(1, 2);
  print('$result');
 }
