Extracting Information from a Scanned Gs1-Type Barcode

Barcode scanner data extraction

Are you making your own codes or just scanning for example a store bought product? usually stores don't store that kind of details on their barcodes neither should them, with no database would be kinda hard to make discounts in certain occasions. My advice is to be more clear on what you pretend. Anyway just download a barcode app for mobile and try to see what an regular barcode contains. That may get you going. I used to work in a store that had a database for that, i might be able to help you but need to know more.

Flutter: Get information from scanned barcode number

Well, it seems the only plausible way to do it from Flutter would be to use a barcode lookup API like @RichardHeap proposed in the comments. If my app was Flutter only (without a backend server connected to it) I believe I would have gone that way.

But I guess I'll just send the barcode number itself to the backend and deal with it on the server-side.

Using ZXing natively to get information of product using barcode number

Zxing project does not provide you any information about the manufacturer of the product. You have to do it on your own. Barcode can be read using ZXing and you have to check the corresponding number related to the product which is pre-configured in your database.
