in fragment_update UpadateFragmentArgs lint is showing not recoinzable

Following the ( aweome! ) video tutorial series, I get to the part where I first try to add an item to the ToDo Database... I get the following error

Cannot create an instance of class viewmodel.ToDoViewModel

Can't find any solutions online. Have triple checked the code matches the videos and then tried amended code from GitHub... just can't figure it out. :(

1. Write something in the search menu, example : Empanadas (it works good)
2. Put app in background, wait 5 seconds
3. Put app in foreground-> In search menu appear "Empanadas" yet but the list isn't filtered

I've attached an image with this issue

Should be:

        <item
            android:id="@+id/menu_sortBy"
            android:title="@string/sort_by">
            <menu>
                <group android:checkableBehavior="single">
                    <item
                        android:id="@+id/menu_priority_high"
                        android:title="@string/priority_high"/>
                    <item
                        android:id="@+id/menu_priority_low"
                        android:title="@string/priority_low"/>
                </group>
            </menu>
        </item>

So the radio buttons will be visible in the sub menu and not in the main options menu

I am following your tutorial course and everything works perfectly fine. At the moment I finished the binding.
Since the first moment the only thing that did not work was the color of the priority cardview in the list fragment.
In the other fragments the color for priority works fine.
I analized the database and the priority is ok.
Could you help me?
Thanks Michel

According the docs this line should actually be:
return oldList[oldItemPosition].id == newList[newItemPosition].id
