Add a permanent scan history

[ayecptn]

Problem

As someone who answers a lot of questions on the 'not-completed entries' tab, I cannot use the history to find my own scanned products.
I also cannot use the compare feature on the startpage, as I sometimes clear this list.

Proposed solution

Add a setting to automatically add scanned products to the list 'Scanned Products'.

After activating this setting scanned products get automatically added to the list.
Searching for a EAN does not add it to the list.

The list gets sorted sorted by last added.
The last 10-30 entries should be cached.

Hi @ayecptn!
I think we already have a "scan session" list, that gets deleted with the "clear" button on home page.
What you seem to need is a parallel "scan history" list, that gets each new scanned product (like "scan session"), but that does not get deleted by the "clear" button, right?
The next question is: from where would you get access to that list? From profile / my lists?

[ayecptn]

Yes, that is exactly what I need.

Profile / my Lists is the easiest solution I think.
Another idea that came to my mind right now is to add a tab in the history view. Then you would have 2 tabs in the history, one with all viewed products and one with all scanned products

[monsieurtanuki]

Good!
Another option would be to add a filter in the history page, like "show all items / only the items I scanned".
Then, the question is: how do we keep UX consistency in the app? Why does it make sense to put tabs/filters only in history? Should we put tab/filters in all list pages?

[ayecptn]

Filters would be nice, but I think that should be handeled in another issue by itself.

[M123-dev]

I have to agree with @monsieurtanuki the tab's idea isn't bad, but it cuts into the ux too much.

Would it be good for you to have a filter which stays even if you restart the app.

Somewhat similar to what @teolemon suggested in #1371

[monsieurtanuki]

Anyway the first step is to

• create the new "scanned history" list
• add scanned products to the new "scanned history" list (as well as "scanned session" of course)

The UI/UX could be tested more consistently later with real data: filters? tabs?

[ayecptn]

@M123-dev I am completly fine with a filter.

Anyone ready to implement the "scanned history" product list?
I'm a bit stuck with a temporary limited access to my computer and a limited desire to lose 30 minutes each time I switch to/from flutter 3.0.5/3.7.3 between Smoothie and other projects.

Hey, is this issue assigned? I'd love to work on it if not-

[monsieurtanuki]

Hi @opxdelwin!

Please

• create the new "scanned history" product list
• add each new scanned product to it (same as "scanned session")
• create a new product page based on "scanned history", accessible from profile / my lists. That part may change, but that's a start and it will take 5 minute

[opxdelwin]

So, I'll implement a feature of caching last 30-40 which is accessible from profile -> lists, right?

[monsieurtanuki]

More or less: I wouldn't bother about the 30-40 limit (why 30? why 40? why 100?). Let the user clean the list the way she wants, just add freshly scanned products to a new app product list called "scan history".

[opxdelwin]

Cool, no limit to scanned product history. Now due to complex project structure, it's had to navigate.
So far, I listen to ContinuousScanModel in camera_scan_page.dart to get latestConsultedBarcode and store it in a Hive box. Now we have all the scanned barcodes. Should I be using LocalDatabase or go forward with Hive? Couldn't put much time into this as I have a test tomorrow.

[monsieurtanuki]

@opxdelwin I'm not sure you're going in the right direction: we already use local databases, we already store the product barcode when it's scanned, so please be lazy and stupid and just add "Add barcode to 'scan_history'" when you see "Add barcode to 'scan_session'" in the code.

@opxdelwin Still working on it, or may I code it?
