What steps will clearly show the issue / need for enhancement?
Dart doesn't have option to pass primitive types by reference to functions.
So can you make something like constructors class_name(this.a,this.b) but not the same.

f(a,b)
{
  return [a+b,a*b];
}

void main()
{
  int b = 10;
  int d = 5;
  [b,d] = f(b,d); // i expect here to chance b's value to b+d, d's value
                  // to b*d
}

like this
