1. Choose between `Navigator` (imperative) and `Router` (declarative) based on app complexity.
2. For simple navigation, use `Navigator.push()` and `Navigator.pop()` with `MaterialPageRoute` or `CupertinoPageRoute`.
3. For complex navigation (deep linking, web support), add the `go_router` package and use `MaterialApp.router`.
4. Define routes in the `GoRouter` configuration.
5. Implement nested navigation using a `GlobalKey<NavigatorState>` and `Navigator` widget.
6. Handle back button presses with `PopScope` in nested flows.
