Create a "Add several products" to bulk add products to a list

[teolemon]

Why

• Some people need to create quickly a list of products (for professional/educational/health tracking) purposes
• Currently, they have to scan products one by one, open them, click add to list, select list, validate (ITERATE N times)

What - Proposed solution

• Create a "Add several products" item in the overflow button of a list (we can make it more proeminent at a later time)
• It will open a special scan view, with a simple button "Finish adding to the list"
• All products scanned this mode will be automatically added to the list, until "Finish adding to the list" is tapped.
• We don't need to display the scan card or anything. Just a tooltip: "1345754323 added to TOTO list" is sufficient.

Note

• This would be most valuable if combined with #3830 so that users can get the list for various purposes (we can add value ourselves in the app at a later point)

@teolemon I would suggest a low-tech solution: opening a text edit field where the user could paste a list of barcodes. Then, perhaps, the solution you suggested.

[teolemon]

possibly in two chunks, but this app is mostly about scanning barcodes and fetching information :-)

[monsieurtanuki]

Perhaps pasting a prepared list of 100 barcodes will be faster than scanning them, especially if it's an action to be performed several times on several devices (e.g. lecture/class). A hybrid mode (text field + scan) makes sense.

[teolemon]

I believe most use cases will be people willing to put a lot of products from real life in a list.

@teolemon Given the pain in the neck the scan can be, I would rather suggest:

• the user scans whatevers she wants
• in the "scan session" list (as in all lists) we add a "bulk add to another list" action
• with this action you "check" items before you add them to the second list
