Back button on Android always closes the app

[rignaneseleo]

Hi, I'm on version 7.8.4 and I'm having a problem with navigation on Android 14: when I press the phone back button on any page of the app, it closes instead of executing the pop() function. The onWillPop functions are never triggered.

I read #1391 and tried to manually set the backButtonDispatcher to ChildBackButtonDispatcher( Router.of(context).backButtonDispatcher!) but the app crashes with error "Router operation requested with a context that does not include a Router."

This is my app.dart:

import 'package:auto_route/auto_route.dart';
import 'package:firebase_analytics/firebase_analytics.dart';
import 'package:flutter/material.dart';
import 'package:flutter_localizations/flutter_localizations.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'package:flutter_translate/flutter_translate.dart';
import 'package:parenthood/router/router.dart';
import 'package:parenthood/router/router_provider.dart';
import 'package:parenthood/theme/theme_definition.dart';

class App extends StatefulWidget {
  const App({Key? key}) : super(key: key);

  @override
  State<App> createState() => _AppState();
}

class _AppState extends State<App> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    var localizationDelegate = LocalizedApp.of(context).delegate;

    return LocalizationProvider(
      state: LocalizationProvider.of(context).state,
      child: Consumer(
        builder: (context, ref, child) {
          final appRouter = ref.watch(routerProvider);

          return MaterialApp.router(
            key: Key(localizationDelegate.currentLocale.languageCode),
            theme: defaultTheme(),
            debugShowCheckedModeBanner: false,
            title: translate("brand"),
            routerDelegate: AutoRouterDelegate(
              appRouter,
              navigatorObservers: () => [
                FirebaseAnalyticsObserver(analytics: FirebaseAnalytics.instance)
              ],
            ),
            routeInformationParser: appRouter.defaultRouteParser(),
            supportedLocales: localizationDelegate.supportedLocales,
            locale: localizationDelegate.currentLocale,
            localizationsDelegates: [
              localizationDelegate,
              GlobalMaterialLocalizations.delegate,
              GlobalWidgetsLocalizations.delegate,
              GlobalCupertinoLocalizations.delegate,
            ],
          );
        },
      ),
    );
  }
}

Removing android:enableOnBackInvokedCallback="true" from my <application> tag in AndroidManifest.xml fixed the problem.
