dartmethod-cascades

Any way to get the return value of last method in cascade?

I'm doing something like this:

new A()
  ..methodA()
  ..methodB()
  .toString();

Should this return the result of toString()? Currently it's returning the new A object.

Solution

  • In your code toString() is applied on the result of methodB(). It's like you are doing :

    var func = (o) {
  o.methodA();
  o.methodB().toString();
  return o;
};
func(new A());

    To do what you want, you have to do something like : 

    (new A()
  ..methodA()
  ..methodB()).toString();
