Ref<T> class

A reference to a value.

The reference will persist until the component is removed from the node hierarchy.

Changing the value of the reference does not force a rerender of the component. But it is possible to add a listener to the stream of change events.

If the initial value of the reference is not null, then this value will be added to the stream of change events.
