BaseNavigationInteractor<IState, Input, AppTabType, RoutesClassType extends RoutesBase, DialogClassType extends RoutesBase, BottomSheetClassType extends RoutesBase, RouteType, DialogType, BottomSheetType, DeepLinksInteractorType extends BaseDeepLinksInteractor> class abstract

Base class for navigation interactor Contains state and input parameters as every other interactor Also you need to specify type parameters for tabs, routes, dialogs and bottom sheets

You need to specify custom route builder or provide UINavigationSettings values at app startup

Example:

@singleton
@AppNavigation(tabs: AppTab)
class NavigationInteractor
    extends NavigationInteractorDeclaration<NavigationState> {

  @override
  AppTab? get currentTab => state.currentTab;

  @override
  Map<AppTab, GlobalKey<NavigatorState>> get currentTabKeys => {
        AppTabs.posts: GlobalKey<NavigatorState>(),
        AppTabs.likedPosts: GlobalKey<NavigatorState>(),
      };

  @override
  NavigationInteractorSettings get settings => NavigationInteractorSettings(
        initialRoute: RouteNames.home,
        tabs: AppTabs.tabs,
        tabViewHomeRoute: RouteNames.home,
        initialTabRoutes: {
          AppTabs.posts: RouteNames.posts,
          AppTabs.likedPosts: RouteNames.likedPosts,
        },
        appContainsTabNavigation: true,
      );

  @override
  Future<void> onBottomSheetOpened(Widget child, UIRouteSettings route) async {
    // ignore
  }

  @override
  Future<void> onDialogOpened(Widget child, UIRouteSettings route) async {
    // ignore
  }

  @override
  Future<void> onRouteOpened(Widget child, UIRouteSettings route) async {
    if (route.global) {
      app.eventBus.send(GlobalRoutePushedEvent(replace: route.replace));
    }
  }

  @override
  void setCurrentTab(AppTab tab) {
    updateState(state.copyWith(currentTab: tab));
  }

  @override
  NavigationState get initialState => NavigationState(
        currentTab: AppTabs.posts,
      );
}
