authservice | Move OIDC token acquisition out of your app code | Authentication library

Everytime I publish my Blazor Server-project to my website domain, and opening the website, this exception occurs, and there's little to no help Googling it:

And it says AppState.cs: line 21, so here's the codeline for it:

This exception is not happening under debugging localhost. When I delete localStorage from the browser on my website, and refreshing, then everything works. But I don't want my customers having this exception and having to tell them to delete the localstorage everytime I'm publishing.

My Program.cs if necessary:

I am trying to figure out how to make use of Firebase's onAuthStateChanges() stream to use as a Listenable in the refreshListenable parameter from the go_router package to redirect whenever the authState changes. In additon I am using flutter_riverpod for State Mangement.

My code looks like this so far:

I created a simple AuthService class (shrinked down to the most important parts):

Apparently throwError(error) is now deprecated. The IntelliSense of VS Code suggests throwError(() => new Error('error'). new Error(...) accepts only strings. What's the correct way to replace it without breaking my HttpErrorHandlerService ?

I put this.useraccountsubject(user) to interpolate information on login, but I get an error :

ErrorType: this.useraccount.next(user) then Error An argument of type 'HttpResponse' is not allowed against a balance of 'Useraccount'

I'm new to flutter and i'm trying to make firebase sign in using email and password!

everything works fine within the console but at the app it doesn't take me to the home page with correct credentials!

I am using a stream builder that reacts to the Firebase user state. I am in "Landing Screen", and I push "Login Screen" on top of it. After I log in, the Stream Builder replaces the "Landing Screen" with "Discover Screen" correctly. However, the pushed "Login Screen" remains on top of "Discover Screen".

How do I use Stream Builder to also replace the pushed widgets from Navigator?

Here is the code:

I just created an ion-select in ionic version 6. My problem is that i have successfully pre selected a value when the page loads, but this pre select value does not get shown in the UI?!

It just appears after I have clicked the select, but before it does not appear (as you can see on pic 2). I load the data in the ionViewWillEnter Method and pre select it with an NgModel!

You can see it here:

Looks like this when the page was loaded

Looks like this when I open the select (pre select value was succesful

I am working on an application in which I am implementing custom permission. There is subscription-based permission that I can't check in auth guard which will be static and I have implemented helper for permission which checks for route and then check it in user subscription for that route and then redirected to any of the pages on role permission. It is working fine but I need a better approach to implement it with clean code. Here is my implementation
