What’s a good recipe for overriding hashcode in Dart?

by

The quiver package provides helper functions hash2, hash3, etc., which simplify the task of implementing hashCode, with some assurance that it works properly under the Dart VM and when compiled to JavaScript.

import 'package:quiver/core.dart';

class Person {
  String name;
  int age;

  Person(this.name, this.age);

  bool operator ==(o) => o is Person && name == o.name && age == o.age;
  int get hashCode => hash2(name.hashCode, age.hashCode);
}

Also see this post for a slightly lengthier discussion.
