How to use google vision API within a Flutter app

I want to create an app (build by Flutter), which uses OCR features of google cloud vision (https://cloud.google.com/vision/). In the app, taking a picture by camera, and use gooogle cloud vision to extract text from it.
I found several resources, but I am not sure which one is the right one.
1)https://pub.dev/documentation/googleapis/latest/vision.v1/vision.v1-library.html
2)https://cloud.google.com/vision/docs/reference/rest#service-endpoint
3)https://pub.dev/packages/google_ml_vision
My question is
which one above that I can use with my Flutter app?
the first and the third are the same thing?
Is there any example of using the first and second approach.
Thanks very much.

Single UITest case on two simulators

I’m new in UITesting and I’m searching for any info about how to test this kind of case:
1. I have a single uitest
2. I need to start two simulators for each user
3. Then I want to do some interactions on those simulators (like log in on both, join a “room” on first and second and then check on first if second user is in “room” (it's a bit like uitesting messaging app))
Can I do this in XCode or I will need some external tools? Where can I search for more info? Maybe I should use different approach?

Revoking an app in Google Play Store - can the same name/title be used again?

Due to a well known and quite often discussed "keystore-signing-problem" I need to rebuild my app from scratch again in Google Play Store.
However I wonder: In case the "old" app will be disabled - can I use the same name for the "new" app again?
The two important things you need to pay attention to are the signing hash and the package name. You can only have a single app published per combination of SHA1 hash/package name. All other fields (title, app name, etc) and configuration within your Android app can be set to whatever you want and you should have no trouble with conflicts.

Google Play Store: How to "lock-up" an app name

Scenario
I have an app that I've been working on for 6 months. I have already made the app for native iOS and about to put it on the Apple App Store. I know that I will want to work on the Android version of the app starting soon, but I would like to "lock-up" the name of the app on the Google Play Store before I begin working on it. I would hate to work another 6 months working just to get to the end and find that someone else took that name.
Question
How do I save an app name on the Google Play Store for future distribution?
You don't need to, Duplicates of names are allowed in Google Play. :)

Xcode and data - 'cloud' or local?

I am new to learning xcode, and started a simple project which main goal is for me learn Xcode.
The project is a simple app that keeps track of scores in a cardgame.
Sofar it is just for fun, for me and the guys I play cards with.
But heres an issue:
I would like to make it possible that it doesnt matter whose Iphone we are using.
Anyone with the app should be able to log in and see all of our gamescores.
That should be easy. Me and my friends could create a group, in which all of our games are stored.
Other people can create their own group, inwhich they can store theirs.
BUT where should I store the data, when building the app?
Potentially there could be a LOT of data, if a lot of people downloads the app, and plays a lot of cards!
I am a webprogrammer, and am used to working with PHP and mySQL.
Whats the smart way to deal with this?
Thanks
John
You should consider using the GameKit framework, might be best suited for your needs.
