feat: #370 - added "uuid" to configuration

[monsieurtanuki]

Impacted files:

• configuration_test.dart: added tests with "uuid"
• HttpHelper.dart: included new static uuid to parameters
• OpenFoodAPIConfiguration.dart: added static String? uuid
• pubspec.yaml: unrelated upgrade

[M123-dev]

Looks good thanks @monsieurtanuki

Thank you @M123-dev for your review!
Now the trick is to tell developers to use user agent and uuid, but that's beyond my coding abilities ;)

@monsieurtanuki thank you for the changes. Maybe updating the readMe and the example file can help ?
So by default when someone will start coding with OFF package will coy/paste the example with the uuid

[M123-dev]

That's something we can add to https://github.com/openfoodfacts/openfoodfacts-dart/projects/2

Fair enough @MohamedFBoussaid, but I don't know

1. which values can be set - strict UUID format or just a String?
   => probably just a String
2. how the developers get a UUID - they just import whatever uuid package or they call an OFF dedicated API, as @jasmeet0817 feared that UUID may not be unique if generated locally (if I remember well)
   => probably locally with a package - cf. Implement the new App uuid system #370 (comment)
3. when the UUID must be set
   => probably at the very first init of the app, and saved in preferences

It's looked so far like uuid should be populated by a device id, but that's not supported by (agnostic) dart. Only by flutter.

@monsieurtanuki I can give it a try with my Flutter app, and see how it will work. And then I will be back with examples

Future<String?> _getId() async {
var deviceInfo = DeviceInfoPlugin();
if (Platform.isIOS) { // import 'dart:io'
var iosDeviceInfo = await deviceInfo.iosInfo;
return iosDeviceInfo.identifierForVendor; // unique ID on iOS
} else {
var androidDeviceInfo = await deviceInfo.androidInfo;
return androidDeviceInfo.androidId; // unique ID on Android
}
}

Thank you @MohamedFBoussaid!
I would rather use platform_device_id instead (no ifs), but the result should be similar.

[MohamedFBoussaid]

Thanks @monsieurtanuki I will use that package.

[MohamedFBoussaid]

@monsieurtanuki , I have made a quick test using that package. And normally I made a fake update for a product 7613035989535 with the following UUIDs :

• iPhone: 1723BE2C-C0EB-4055-8960-5534AFBFB63F.
• Android : 377654b1f5c4a080

@stephanegigandet @teolemon is there a way to check if the UUID was received on the backend ?

I've just added uuid to smoothie too (openfoodfacts/smooth-app#1064)
