distinctUnique method

Stream<T> distinctUnique (
  1. {bool equals(
    1. T e1,
    2. T e2
  2. int hashCode(
    1. T e

WARNING: More commonly known as distinct in other Rx implementations. Creates a Stream where data events are skipped if they have already been emitted before.

Equality is determined by the provided equals and hashCode methods. If these are omitted, the '==' operator and hashCode on the last provided data element are used.

The returned stream is a broadcast stream if this stream is. If a broadcast stream is listened to more than once, each subscription will individually perform the equals and hashCode tests.
