google vr sdk has no demoscenes - unity3d

I'm trying to import the google vr sdk to unity. Where the googlevr package has no demoscenes. Instead it has only the demo.
enter image description here
this is how I get demo in google vr how to add this sdk and make it into a sterographic view(actual picture of the tutorial.Here it is "DEMOSCENES". But for me I get it as "demo")
(the video link of the tutorial
check the video from 3:45:-
https://www.youtube.com/watch?v=cK1_EnZkwCE )

There should be one demo scene called "ControllerDemo" in the ControllerDemo folder and another demo scene called "DemoScene" in the HeadsetDemo folder.
You have not clicked on any these folders yet based on your screenshot. You are currently inside the DemoScenes folder.
If you into those two folders and don't see the demo scenes then get the latest Google SDK from this link.

The package is corrupted, you can see the many problems in the issues section. Unity runs better on flutter using this package. You can see a full integration example we created in this repo.

Why the integration of Flutter with Unity and AR Vuforia makes no object appears?

I want to integrate Flutter app with Unity and AR Vuforia. I tried to use library: flutter_unity_widget (https://pub.dev/packages/flutter_unity_widget).
When integrating Flutter app with Unity without Vuforia it works very well. But when I tried to use it with Vuforia … OK, I didn't get any error and I could build app, but when I tested it, it didn't show any object.
I did all the configuration with the library tutorial.
Maybe some of you integrated something like that?
Do you have any sample project with it?
You can check out this blog about "Building with Flutter + Unity (AR Experience Toolkit)" for unity.
And for AR Vuforia, it seems that support for this is not yet materialized as of this GitHub post. You can watch out for the updates there.
The same thing happened to me when I was testing on iOS, Android was OK
I went through all the steps, only that Vuforia didn't recognize anything. According to this issue Dataset Foo could not be loaded and cannot be activated, I dragged and dropped the data folder and Vuforia into the Runner.
And everything was working fine

Vuforia plugin disappears on unity

On my Mac, I noticed every time I open my AR project which uses Vuforia, the Vuforia plugin disappears and I have to go to the unity download page and redownload the Vuforia sdk. Any suggestions on why this is happening or has anyone had this problem?
I figured it out. I'm kind of new to Mac and I copied the unity app into the applications folder and then when I imported the Vuforia package it imported it to the original location of the Unity app, so when I open it from the original location it worked and when I opened it in the app location Vuforia didn't work

how to get my app to recognize images from the cloud?

I can't figure out how to get my Unity app to recognize images from the cloud using the Metaio SDK. Could anyone point me to the method, API or tutorial to allow this on Unity/Metaio?
For example, I've got my Unity app working with Metaio to recognize a local image, that is, an image that I've placed in the Resources folder. I would like to build an app that can recognize images in the cloud (metaio servers) such that no image file would need to be bundled into the application itself.
Some details: I'm using Unity Pro 4.5.5 with Metaio SDK 6.0, trying to build an app for Android
The Metaio SDK installer includes example of Cloud based image recognition a.k.a. Visual Search. Please refer to the Visual Search scene in the Unity example. More information can be found here: https://dev.metaio.com/visual-search/general-information/
