#Preview {    
    MainActor.assumeIsolated{
        let config = ModelConfiguration(isStoredInMemoryOnly: true)
        let container = try! ModelContainer(for: NoteBackground.self, configurations: config)

        let background = NoteBackground(id: "0", image: "bird",createdAt: Date.now.addingTimeInterval(2*100))
        container.mainContext.insert(background)
            
        let background2 = NoteBackground(id: "1", color: "#223233", textColor: "#000", createdAt: Date.now.addingTimeInterval(2*100))
        container.mainContext.insert(background2)
        
        return
            NavigationStack{
                UpsertView(note: Note())
        }
        .modelContainer(container)
}
  
}
