Matthias Kunnen b5551609fe fix(router): fragment can be null (#37336)
ActivatedRoute.fragment was typed as Observable<string> but could emit
both null and undefined due to incorrect non-null assertion. These
non-null assertions have been removed and fragment has been retyped to
string | null.

BREAKING CHANGE:
Strict null checks will report on fragment potentially being null.
Migration path: add null check.

Fixes #23894, fixes #34197.

Angular Router

Managing state transitions is one of the hardest parts of building applications. This is especially true on the web, where you also need to ensure that the state is reflected in the URL. In addition, we often want to split applications into multiple bundles and load them on demand. Doing this transparently isnt trivial.

The Angular router is designed to solve these problems. Using the router, you can declaratively specify application state, manage state transitions while taking care of the URL, and load components on demand.
