Exclude items from autosuggestions

[monsieurtanuki]

Why - Problem description

cf. openfoodfacts/smooth-app#5096 by @g123k:

In many parts of the edition, we have an auto-completion feature.
However, this is a nonsense to list an item… which is already selected.

What - Proposed solution

The first thing to do would be to add a parameter to the autosuggestion methods: a list of items to exclude.
Then, if the developer asks for 10 items and we exclude 2 items, we should ask the server for 10+2 = 12 items and return the first 10 items that are not in the 2-item list.

Alternatives you've considered

Of course if the server could accept a list of items to exclude it would be better.

i tried to add this approch in the open_food_search_api_client.dart file :

1. We will add a new parameter called excludedItems to the autocomplete function. This allows developers to pass a list of items they want to exclude from the suggestions.

2. Inside the function, we first check if the excludedItems list is empty or not provided. If it is empty, we simply return the original list of suggestions as it is.

3. If the list is not empty, we remove any items in the suggestions that are also in the excludedItems list.

4. Finally, we return the filtered list of suggestions where the excluded items are no longer present.

is this a valid apporch or it should be in a different file ? or any other imporved method ?

@AffanShaikhsurab That's good but you're missing a detail: you have to ask for more items, as explained in the OP.
