Angular executes a *pure pipe* only when it detects a *pure change* to the input value.
|
|
In Angular Dart, a *pure change* results only from a change in object reference
|
|
(given that [everything is an object in Dart](https://www.dartlang.org/docs/dart-up-and-running/ch02.html#important-concepts)).
