Unable to navigate accross child modules

[agustin-garcia]

Hello, I have the following code structure and modules, but I can't figure it out on how to navigate from Login Module (once it's been authenticated) to the AppHomeModule.

class AppModule extends Module { @override List<ModularRoute> get routes => [ ModuleRoute('/', module: AppInitialModule(), guards: [AuthGuard()]), ModuleRoute('/home_modular', module: AppHomeModule()), ModuleRoute('/login_modular', module: LoginModule()), ]; } class LoginModule extends Module { @override List<ModularRoute> get routes => [ ChildRoute('/', child: (_, __) => LoginWidget()), ]; } class AppHomeModule extends Module { @override List<ModularRoute> get routes => [ ChildRoute('/', child: (_, __) => HomeWidget(),), ChildRoute('/home_widget', child: (_, __) => HomeWidget(),), ]; }

On the LoginService, once User has been authenticated I try to navigate to HomeModule by using the following scenarios (once at the time), but none of them work:

Modular.to.navigate('/home_modular/'): It apparently initiates de the HomeMoule (as intended) based on the message: "AppHomeModule INITIALIZED", but it doesn't navigate anywhere (I mean, the App stays on the Login page)

Modular.to.navigate('/home_modular/home_widget/'): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: RouteNotFoundException: Route (/home_modular/home_widget/) not found

Modular.to.navigate('/home_modular/home_widget'): It apparently initiates de the HomeMoule (as intended) based on the message: "AppHomeModule INITIALIZED", but it doesn't navigate anywhere (I mean, the App stays on the Login page)

I'm testing this on: flutter_modular: ^5.0.3 Android Emulator: 12.0 (S) - API 31 Emulator Version: 33.1.24-11237101 Flutter (Channel stable, 3.16.9, on Microsoft Windows [Version 10.0.22631.3155], locale en-US) Windows Version (Installed version of Windows is version 10 or higher) Android toolchain - develop for Android devices (Android SDK version 34.0.0) Android Studio (version 2023.1)

@agustin-garcia,

This correct is Modular.to.navigate('/home_modular/')

You did it (routeInformationParser, routerDelegate) ?

import 'package:flutter/material.dart';
import 'package:flutter_modular/flutter_modular.dart';

void main() {
  return runApp(ModularApp(module: AppModule(), child: AppWidget()));
}

class AppWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return MaterialApp.router(
      title: 'My Smart App',
      theme: ThemeData(primarySwatch: Colors.blue),
      routeInformationParser: Modular.routeInformationParser,
      routerDelegate: Modular.routerDelegate,
    ); 
  }
}
