The getting started guide takes you from install to<br>navigating with typed routes in a few minutes — sealed class, exhaustive<br>switch, done.

Sealed routes, exhaustive builds<br>Navigation is a switch over a sealed type. Add a route and the compiler<br>finds every place that must handle it — no runtime “unknown route” left.

The stack is a value<br>Your history is a List of route objects. Push, pop, and set are list<br>operations — testable without a widget tree, restorable across process<br>death.

Every navigation. One observer.<br>Register a standard NavigatorObserver once — it sees tab switches and<br>adaptive in-place changes that produce no route event in other routers.
