zenrouter

⚠️ Breaking Changes

• GuardRule contract renamed (via zenrouter_core 2.3.0). The 2.2.0 methods are removed:

  Removed	Replacement
  canPop(route)	canPopRule(route) / canPopRuleWith(coordinator, route)
  canPopListenable(route)	canPopListenableRule(route) / canPopListenableRuleWith(coordinator, route)
  guard(coordinator, route)	guardRule(route) / guardRuleWith(coordinator, route)

  Use route-only methods when no coordinator is needed; override *With for dialogs / app state. Each *With defaults to its non-With counterpart.

  // Before
  class UnsavedChangesRule extends GuardRule<AppRoute> {
    @override
    bool canPop(AppRoute route) => !route.hasUnsavedChanges;
  
    @override
    FutureOr<bool?> guard(Coordinator c, AppRoute route) async =>
        showDiscardDialog(c.navigator.context);
  }
  
  // After
  class UnsavedChangesRule extends GuardRule<AppRoute> {
    @override
    bool canPopRule(AppRoute route) => !route.hasUnsavedChanges;
  
    @override
    FutureOr<bool?> guardRuleWith(Coordinator c, AppRoute route) async =>
        showDiscardDialog(c.navigator.context);
  }
  

🚀 New Features

• RouteGuard.canPopWith / canPopListenableWith: Coordinator-aware PopScope hints; NavigationStack prefers these when a coordinator is present.
• RouteGuardRule.popGuard: Runs the guardRule chain without a coordinator.

📖 Documentation

• Recipe / example / mixins API updated for the dual guardRule / guardRuleWith API.

🚀 New Features

RouteGuardRule — composable pop guards

• New GuardRule / RouteGuardRule API (via zenrouter_core 2.1.0) for reusable leave-confirmation chains — first non-null bool wins (null = continue).
• RouteGuard.canPop / canPopListenable drive Flutter PopScope; programmatic pop still always consults popGuard / popGuardWith.
• Flutter bridges: toListenableMixin() / toFlutterListenable(); NavigationStack rebuilds PopScope via ListenableBuilder when a listenable is present.

⚠️ Breaking Changes

• CoordinatorCore.pop: Pops only the nearest eligible path (no longer multi-path in one call). Bumped zenrouter_core to 2.1.0.
• RouteRedirect.resolve: Throws StateError on redirect type mismatch.

📖 Documentation

• New Recipe: Composable Route Guard Rules
• Example: example/lib/main_guard_rules.dart
• API: Mixins — guard rules section

• Bump zenrouter_core version to 2.0.3

🚀 New Features

CoordinatorView — headless coordinator embed

• New CoordinatorView widget renders a coordinator via layoutBuilder without Flutter's Router—for super apps, parallel panels, plugin surfaces, and other host-owned shells.
• Optional initialUri seeds navigation once when coordinator.root.stack is empty (ignored after the embed has stack state or on remount with the same coordinator).
• Supports sync and async parseRouteFromUri for the initial bootstrap.

CoordinatorLayoutBuilder mixin

• Extracted layoutBuilder(BuildContext) into CoordinatorLayoutBuilder; CoordinatorLayout implements it so embed hosts can depend on layout rendering without RouterConfig.

⚠️ Breaking Changes

• layoutBuilder moved to CoordinatorLayout: Override layoutBuilder on your coordinator's CoordinatorLayout mixin (unchanged for typical extends Coordinator subclasses). It is no longer declared on the Coordinator class body.
• RouteLayoutBuilder signature: The first parameter is now CoordinatorCore instead of Coordinator. Update custom defineLayoutBuilder / kDefaultLayoutBuilderTable callbacks accordingly (cast to Coordinator when you need Flutter-specific APIs).
• RouteLayout.buildRoot: Now accepts CoordinatorLayout instead of Coordinator. Call sites that passed a bare CoordinatorCore must use a type that provides getLayoutBuilder / root.

📖 Documentation

• New Guide: CoordinatorView — embed patterns, initialUri semantics, pitfalls vs MaterialApp.router
• API: Coordinator API — CoordinatorView section and dual quick-start
• Roadmap: Embedded / multi-surface learning path in DOCUMENTATION_ROADMAP

• Fix: CoordinatorModular.getModule now correctly resolves the coordinator itself — runtimeType: this is registered in _allModules, enabling getModule<MyCoordinator>() to work at any level of the hierarchy. (Bumped zenrouter_core to 2.0.2)

• Fix: Fix CoordinatorModular edgecase cascading dispose and prevent duplicate definitions. (Bumped zenrouter_core to 2.0.1)

• Fix: Revert hasEmptyPath back to pathSegments.isEmpty in resolveInitialUri for correct path empty checks.
• Refactor: Remove redundant initialRouteInformation parameter from CoordinatorRouteInformationProvider since fallback defaults and resolution logic is robust now.

🎉 Major Release - Core Architecture & Layouts

🚀 New Features

• zenrouter_core Package: Extracted all platform-independent core routing types (RouteTarget, CoordinatorCore, StackPath, and route mixins) into a new dedicated package.
• Composable Redirects: You can use RouteRedirectRule as RouteRedirect to allow composable, testable redirect logic via multiple rules (e.g., StopRedirect, ContinueRedirect, RedirectTo).
• Route Identity updates: Introduced RouteUri abstract class (and RouteUnique) to centralize URI-based identity for coordinator-managed routes.

⚠️ Breaking Changes

• Layout Binding Refactoring: The global RouteLayout.defineLayout has been removed. You must now bind layouts to paths using the StackPath.bindLayout() cascade syntax (e.g., NavigationPath.createWith(...)..bindLayout(HomeLayout.new)), or use defineLayoutParent() / defineLayoutBuilder() inside the coordinator.
• Core Mixins Relocated: Core routing types have been consolidated under zenrouter_core. The main package still exports them, but any explicit deep imports to old paths must be updated.
• RouteLayout.definePath Deprecated: Deprecated RouteLayout.definePath in favor of coordinator.defineLayoutBuilder.

📖 Documentation

• Architecture Overview: Completely redesigned READMEs to highlight the layered architecture and paradigm decisions.
• API Reference: Rewrote coordinator, mixins, and navigation paths API references from source.

🐞 Fixes

• Fix: Regression error when using RouteRedirectRule inside IndexedStackPath (Thanks to @obenkucuk)

🚀 New Features

Coordinator as RouteModule — Nested Coordinators

• Coordinator now implements RouteModule<T>, enabling any coordinator to be nested inside a CoordinatorModular by overriding the coordinator getter.
• Unlocks route versioning (V1/V2 side by side), multi-team modular architectures, and deeply nested coordinator hierarchies.
• Auto-detected isRouteModule flag controls root path creation vs parent inheritance.
• See Guide & example/lib/main_coordinator_module.dart

⚠️ Breaking Changes

• Coordinator.parseRouteFromUri signature changed from FutureOr<T> to FutureOr<T?>. Child coordinators return null for unrecognized URIs; standalone coordinators are guarded by assertions.
• CoordinatorModular.parseRouteFromUri returns null instead of notFoundRoute when the coordinator is itself a nested module.

📖 Documentation

• New Guide: Coordinator as RouteModule
• New Recipe: Route Versioning

• BREAKING CHANGE: Remove coordinator from defineModules, use this getter instead.
• Feat: Enforce getModule method return exact type.

🎉 Major Release - Production Ready

🚀 New Features

CoordinatorModular - Modular Route Management

• Split route management across independent modules by domain/feature
• CoordinatorModular mixin + RouteModule base class
• Perfect for large apps with team collaboration
• See Guide & example/lib/main_modular.dart

class AppCoordinator extends Coordinator<AppRoute>
    with CoordinatorModular<AppRoute> {
  @override
  Set<RouteModule<AppRoute>> defineModules() => {
    AuthModule(this),
    ShopModule(this),
  };
}

RouteRedirectRule - Composable Redirect Logic

• Reusable, chainable redirect rules (auth → feature flags → logging)
• RedirectResult sealed class with Stop/Continue/RedirectTo variants
• Async support for API calls, database queries

class ProtectedRoute extends AppRoute
    with RouteRedirect, RouteRedirectRule {
  @override
  List<RedirectRule> get redirectRules => [
    AuthenticationRule(),
    PermissionRule(permission: 'admin'),
  ];
}

⚠️ Breaking Changes

Removed deprecated APIs:

• RouteLayout.buildPrimitivePath → Use RouteLayout.buildPath
• RouteLayout.layoutBuilderTable → Use RouteLayout.buildPath
• RouteLayout.navigationPath/indexedStackPath → Use NavigationPath.key/IndexedStackPath.key
• routerDelegateWithInitialRoute → Use RouteRedirect in IndexRoute

See Migration Guide for details.

    );
