Hi Jordan - I actually have a very similar issue. I'm following an AWS tutorial, which up until today, after I updated my Android SDK, I haven't had too much of an issue. Here's my stuff - I'm a beginner at this so I might have messed something up, but it had been working fine until today. Here's my main dart file import 'package:reaqtionsapplication/reaqtions_app.dart';
import 'package:flutter/material.dart';
import 'package:amplify_flutter/amplify_flutter.dart';
import 'package:amplify_auth_cognito/amplify_auth_cognito.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';
import 'amplifyconfiguration.dart';
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
bool isAmplifySuccessfullyConfigured = false;
try {
await _configureAmplify();
isAmplifySuccessfullyConfigured = true;
} on AmplifyAlreadyConfiguredException {
debugPrint('Amplify configuration failed.');
}
runApp(
ProviderScope(
child: ReAQtionsApp(
isAmplifySuccessfullyConfigured: isAmplifySuccessfullyConfigured,
),
),
);
}
Future<void> _configureAmplify() async {
await Amplify.addPlugins([
AmplifyAuthCognito(),
]);
await Amplify.configure(amplifyconfig);
}And here is the app file import 'package:reaqtionsapplication/features/airquality/ui/aqi_list/aqi_list_page.dart';
import 'package:flutter/material.dart';
import 'package:go_router/go_router.dart';
import 'package:amplify_authenticator/amplify_authenticator.dart';
import 'package:reaqtionsapplication/common/navigation/router/routes.dart';
import 'package:reaqtionsapplication/common/utils/colors.dart' as constants;
class ReAQtionsApp extends StatelessWidget {
const ReAQtionsApp({
required this.isAmplifySuccessfullyConfigured,
Key? key,
}) : super(key: key);
final bool isAmplifySuccessfullyConfigured;
@override
Widget build(BuildContext context) {
final router = GoRouter(
routes: [
GoRoute(
path: '/',
name: AppRoute.home.name,
builder: (context, state) => isAmplifySuccessfullyConfigured
? const AQIListPage()
: const Scaffold(
body: Center(
child: Text(
'Tried to reconfigure Amplify; '
'this can occur when your app restarts on Android.',
),
),
),
),
],
errorBuilder: (context, state) => Scaffold(
body: Center(
child: Text(state.error.toString()),
),
),
);
return Authenticator(
child: MaterialApp.router(
routeInformationParser: router.routeInformationParser,
routeInformationProvider: router.routeInformationProvider,
routerDelegate: router.routerDelegate,
builder: Authenticator.builder(),
theme: ThemeData(
primarySwatch: constants.primaryColor,
backgroundColor: const Color(0xff82CFEA),
),
),
);
}

However, when retrieving the user session I get an Amplify Exception:
may main.dart:
`import 'package:amplify_auth_cognito/amplify_auth_cognito.dart';
import 'package:amplify_authenticator/amplify_authenticator.dart';

void main() {
runApp(const MyApp());
}
class MyApp extends StatefulWidget {
const MyApp({Key? key}) : super(key: key);
@OverRide
State createState() => _MyAppState();
}
class _MyAppState extends State {
@OverRide
void initState() {
super.initState();
_configureAmplify();
}
void _configureAmplify() async {
try {
await Amplify.addPlugin(AmplifyAuthCognito());
await Amplify.configure(amplifyconfig);
print('Successfully configured');
} on Exception catch (e) {
print('Error configuring Amplify: $e');
}
}
Future isUserSignedIn() async {
final result = await Amplify.Auth.fetchAuthSession();
return result.isSignedIn;
}
@OverRide
Widget build(BuildContext context) {
return Authenticator(
child: MaterialApp(
builder: Authenticator.builder(),

return const Center(
child: CircularProgressIndicator(),
