error in firebase-get-to-know-flutter codelab page

In main.dart code of 5th steps(add RSVP functionality) in firebase-get-to-know-flutter codelab page

routes: [
GoRoute(
path: 'forgot-password',
builder: (context, state) {
final arguments = state.queryParameters; // This code seems being written incorrectly
return ForgotPasswordScreen(
email: arguments['email'],
headerMaxExtent: 200,
);
},
),
],

I think it needs to be modified like below
final arguments = state.uri.queryParameters;

Thank you
