The ViewportResizer
is an abstract class that specifies a change
function
that returns a stream that fires every time a window resize event is triggered
or emit
is called. The Angular components library provides a
DefaultViewportResizer
implementing ViewportResizer
and a provider
DEFAULT_VIEWPORT_RESIZER_PROVIDER
to use within the application. The
DEFAULT_VIEWPORT_RESIZER_PROVIDER
ensures that there is only one instance of
the ViewportResizer
implementation.
