TicketView | Android library to implement TicketView | Android library

I am just practicing jetpack compose and trying to get used to it and I made a directory inside my app called Views and I am making different kotlin classes inside that directory each with a different composable function for different peices of my UI. The problem is that I cannot call a composable function from a different kotlin file inside other ones.

for example i have a class Ticket with composable TicketView function

So I'm working on my own SwiftUI project to try and figure out how to integrate SwiftUI with CoreData for data persistence. I've ran into a bit of trouble and I'm trying to figure out how to Fetch a User Entity that I create in the "SignUp View" or an existing user from the "Login View" and how to pass that User object onto the ContentView, which is the first View that appears once the user is logged in.

First of all I'm not sure if I should be using a @Binding property wrapper inside the ContentView in order to capture the object that is passed in from the "Login View" or "SignUp View", or if I should be using just a constant but without a wrapper (I'm guessing that @Binding is the way to go here, but I'd like some clarification on that).

Second, I'm trying to figure out why adding the @Binding wrapper forces the preview to add a comma prior to entering the selectedUser property? Also, how would I go about addressing the Previews error?

Third, I'm a bit confused about when and where I should be importing CoreData. Do I even have to import it? and if so, in which cases do I have to import CoreData?

I know it's a lot of noob questions, but I am a noob and I've been looking all over for the answers and I keep getting different answers wherever I look. Much appreciated. Thanks!

I am working on ticketing system in Flask Admin. The Flask Admin enviroment will be the main one for all the users. For creating or editing tickets I go out from Flask-Admin and use wtforms to implement backend logic. After creation or editing the ticket (validate_on_submit) I want to redirect back to Flask Admin, so I use redirect(url_for(ticket.index_view)). It works fine.

Is there a way to redirect to flask admin, but also with specific filters which were applied before user left Flask admin enviroment? (it is basiccaly GET parameters of url - but in FLASK)

Need help with developing a custom view. This is the kind of view I need to develop:

Have tried a way, but it does not look like a card, its curve and card can be seen in the background. Need something transparent at the cut left and right edges.

Have referred https://github.com/mreram/TicketView, but this does not give a card like effect, need a view with cut edge at left and right in the middle and looks like a card. Any ideas on customizing an image view to look like this ?
