Riverpod FutureProvider - passing result between screens - flutter

Question

I'm learning Riverpod provider and stuck on a topic regarding passing values between screens.
As I learnt from Riverpod docs - it delivers a provider that enables values to be accessed globally... and here is my case.
I'm creating a service repo, that contains some methods delivering futures (e.g. network request to verify user):
class VerifyUser {
Future<User> verifyUser(String input) async {
await Future.delayed(const Duration(seconds: 2));
print(input);
if (input == 'Foo') {
print('Foo is fine - VERIFIED');
return User(userVerified: true);
} else {
print('$input is wrong - NOT VERIFIED');
return User(userVerified: false);
}
}
}
Next step is to create providers - I'm using Riverpod autogenerate providers for this, so here are my providers:
part 'providers.g.dart';
#riverpod
VerifyUser verifyUserRepo(VerifyUserRepoRef ref) {
return VerifyUser();
}
#riverpod
Future<User> user(
UserRef ref,
String input
) {
return ref
.watch(verifyUserRepoProvider)
.verifyUser(input);
}
and there is a simple User model for this:
class User {
bool userVerified;
User({required this.userVerified});
}
I'm creating a wrapper, that should take the user to Homescreen, when a user is verified, or take the user to authenticate screen when a user is not verified.
class Wrapper extends ConsumerWidget {
#override
Widget build(BuildContext context, WidgetRef ref) {
String user = '';
final userFromProvider = ref.watch(userProvider(user));
if (user == 'verified') {
print(userFromProvider);
return MyHomePage();
} else {
return Authenticate();
}
}
}
App opens on Authenticate screen because there is no info about the user.
On Authenticate screen I'm getting input and passing it to FutureProvider for verification.
final vUser = ref.watch(userProvider(userInput.value.text));
When I'm pushing to Wrapper and calling provider - I'm not getting the value I initially got from future.
ElevatedButton(
onPressed: () async {
vUser;
if (vUser.value?.userVerified == true) {
print('going2wrapper');
Navigator.of(context).push(MaterialPageRoute(builder: (context) => Wrapper()));
}},
child: const Text('Verify User'))
Inside Wrapper it seems that this is only thing that I can do:
String user = '';
final userFromProvider = ref.watch(userProvider(user));
But it makes me call the provider with a new value... and causing unsuccessful verification and I cannot proceed to homescreen.
As a workaround, I see that I can pass the named argument to Wrapper, but I want to use the provider for it... is it possible?
I hope that there is a solution to this.
Thx!
