This video is focused on good coding practices when dealing with state management.

When you’re working with a big app that handles state management (in this case with the Provider package), then you should follow this rule:

Never allow your code to alter a list being held in the state management file, from outside.

Instead, create other methods within the ChangeNotifier file that will alter your list.

However, sometimes you need to access the list itself to retrieve some info, right?

That’s where UnmodifiableListView comes in.

It has nothing to do with the ListView widget. Instead, it’s basically an unmodifiable view OF your list.

This allows you to always access a mirror version of your list whenever you need it, while keeping your original list as a private property.
