Instalaci?n

Add the package, then move navigation and overlays into explicit state. Keep imperative push/pop out of the same stack.

Dependencia única

Install with one pub command. No code generation setup is required.

API basada en el estado

You control a List<PageEntry> and optional OverlayRequest as pure state.

Adopción gradual

Start de one feature flow y migrate screen by screen.

Install y Initialize

Use pub add, then wire initial root state para pages y overlay.

Command

Initial app State

import 'package:declarative_nav/declarative_nav.dart';

class _AppRootState extends State<AppRoot> {
  OverlayRequest? _overlay;
  late List<PageEntry> _pages;

  @override
  void initState() {
    super.initState();
    _pages = const [
      PageEntry(key: 'home', name: '/home'),
    ];
  }
}

Constraint

Dentro de una sola pila, PageEntry.key debe seguir siendo único porque se convierte en la identidad de la página de Navigator.
