In my application when I log in on 1 account (lets call him 'user1') and then logout of that user, then I log in on a second account ('user2'), my StreamProvider gets the correct UID from Firebase of the new user, but my StreamProviders below that use that 'uid' still show the data from the previous user.
This is an issue because in, for example, my StreamProvider<List> it gets the workouts from user1, and not from user2,... After HOT RESTARTING the app it will fix itself, but I need it to work without HOT Restarting
So I guess my question is, either, "what am I doing wrong?" or "how can I 'recreate' my StreamProviders (that use the UID) when the value of User/user.uid changes
Thanks in advance
This is the code in my main.dart, which contains all my Providers
void main() {
runApp(MyApp());
}

@override
Widget build(BuildContext context) {
SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,

StreamProvider<User>(

I managed to fix my issue by placing an if around my Multiprovider inside the builder, and either returning my SignIn() screen if user doesn't exist and otherwise I return my multiprovider, containing the providers, and the Wrapper()
This way I force my UI to rebuild on a change in my user provider and by forcing it to rebuild it has to recall my DatabaseService() functions with the new UID
