If i have a string variable like
String name = "Yurani";

And i want to create a node shape by that value, how to do that?

Hi Gian Franco,

thanks for your great work! It would be really helpful if the ARCore Feature to detect images from an AugmentedImageDatabase was available for flutter.
Is this on your list, or is it maybe already possible to use?

Hi, I successfully ran the code but it is giving me an error that "this device does not support AR". After checking the list of AR supported devices on google official website I found that my device "Huawei P20 light" supports AR. So now what can be the issue, help needed?

Is it possible to extract the AR composite views (ArCoreFaceView/ArCoreView, ..) as mediastream videotracks

@giandifra I am exploring AR and your articles and repo has been helpful.
With current plugin, is it possible to:

1. Place the object when plane is detected ?
2. Share the object on other device at the same time ? or let's say draw a line or circle on screen and that is rendered on other device ?

Appreciate your response on this.

Does model needs to be hosted or can we use local file in the url given below:

 ArCoreReferenceNode(

objectUrl: "assets/gltf/1.gltf",
          position: plane.pose.translation,
          rotation: plane.pose.rotation);

Also is there any other way to load local models?

I wanted to test your latest changes for the support of image tracking, but it seems that the latest plugin version 0.0.5+1 is not supporting this example. Might be that the released plugin version is missing the required dependencies.

e.g.: There is no constant named 'AUGMENTEDIMAGES' in 'ArCoreViewType'.

in my flutter 1.9.1 project with android 3.5.1 i can't run the plugin! Just as I can't create sfb because sceneform has a bug. How to solve?

Hi!

It seems that this is the only Flutter Plugin enabling AR.
How may I add a 3D dog to a scene?

I mean, adding just squares, circles and cylinders is useless, and I cannot find any documentation for this library.

Can you help?
Thanks!

Didn't find any reference to it, so can you guys help me know if this plugin support iOS Platform? Thanks

Hi,

is it possible to load from the network, store the usdz and the gltf and pass the path or object to the library to render on the ARKit or ARCore to display it?

i built an application using arcore_flutter plugin. the app works perfectly in debug mode. but it is not working in release mode.
i have attached below the expected and observed outputs of the application kindly help me in resolving the issue.

This is what i get in release mode. i am unable to see the outputs.

This is what i get in debug mode. i can see my outputs(planets).

Kindly help.!!

Hello,

Does this package support devices that are not ArCore compatible?
A message appears?

Thank you

I converted the model from fbx to sfb. It is loaded ok but the part that should be hidden from my head is visible AND is like black wireframe pixelized.
I don't know if it is a problem of the library itself or arscene.

I tried to compile and run the sample app, without any changes, and once you select any option on the menu list, nothing happens.

My phone is a Samsung A70.

At some point, a Java exception is thrown, I don't know if this is the cause:
java.lang.NoSuchFieldError: no "J" field "nativeHandle" in class "Lcom/google/ar/core/Session;" or its superclasses

I found this error while deploying the example to see how it works. It did "flutter pug get" . Getting this error while deploying. Is there anyone who can help me out here? I was about to run in Xiomi A2 lite with android version 9. So, How to solve this problem?

Hello, I have tried your library with its complete configuration but when I do run "flutter run", I am getting this error. Here's the full error stack,

Right now i can only use sfb files present at android/app/src/main/assets/mySFB.sfb. What if i wanted to use sfb file at other directories? like user's sdCard

I've notice that if a node is too distant it's not visible. It seems that the virtual camera has a max render distance. This is a problem because I need to set some distant points

I am trying to replicate the steps mentioned in this article, but seeing crash when app launches.
Appreciate any help in identifying and resolving this crash.

Hey i get some problem here

Looking @ ARCore, I see that the latest version is the 1.17

SceneForm is Archived so no further development on that.

reddit is_sceneform_dead

Are you thinking of moving forward with the development?
To remove SceneForm? (SceneForm 1.16 is opensource and supports only the new gLTF format,
(https://www.khronos.org/gltf/)
Do you need help developing or testing or creating new examples?

Is it possible to detect and read an QR-Code or an barcode with the plugin?

I had tried to install the my demo_app usign the plugin ar_core_flutter on my device BQ then on Google Play Services AR, saids my device is not compatible with this versión!!, the Android System on my device is 8.1.0.

Then I try to install on Galaxy Tab A(2016) SM-T580 Android versión 8.1.0 the result was the same => 'Device is not compatible '

Is it possible to use ARCore and Regular Camera together, have to use some features from regular camera like the Image Streaming.
Is it possible any way to use at least Image Streaming?

When it detects planes showing white dots on surfaces becomes significantly slow and crashes after a few seconds! How can I disable detection of planes?

Great work first of all!

How can we render custom shapes?
Example : I build a 3D model of a product. Is it possible to import it?

Also, is there any implementation of attaching the node to a scene?

like all fucntions of arkit in android https://github.com/olexale/arkit_flutter_plugin

image tracking n etc

please make plugin it helps a lot.

How to run arcore_flutter_plugin on phones with API level less than 24? Is it bounded to API level 24 and higher in this version or there is something wrong with my project? I get Package install error: Failure [INSTALL_FAILED_OLDER_SDK] error after apk installation and trying to run the app on a phone with Android 6!

"obcject3DFileName" is spelled wrong

I see in the example, that I can pass url of the 3d model and library will download it and display. But what if I want to manage cache by myself? I saw in docs, that I have to pass Uri in java/kotlin, how can I pass uri to file from Dart? I've only seen remote url example

I'm trying to implement this plugin and my code is very similar to the example given.

However, whenever I start the app, I get this output. The line I think matters the most is: java.lang.IllegalStateException: Couldn't create Engine

flutter doctor says there are no issues.

Please help, I really need this to work. I've looked everywhere and couldn't find a solution. Thank you!

Here's some more info:
Operating System: Manjaro i3 18.04
CPU: Intel Core i3 (this might be the issue)
Flutter Version: v1.5.4
Android SDK Version: 28.0.3
Android Studio(which I don't use): v3.4

Im trying to use this plugin with:
import 'package:qrscan/qrscan.dart' as scanner;

But when i run:
String barcode = await scanner.scan();

The app crashes, while if i dont put:
ArCoreView(
onArCoreViewCreated: _onArCoreViewCreated,
enableTapRecognizer: true,
)
In my code then it works.

How can i solve this? thank you!

That's the error i get:

Is possibile to check if the ARCore package is installed?
I'm building an app with optional AR code, but ARCore package is usually not installed.
It will also be useful to check if the device is compatible to AR core.

Thanks

how can add text is there any function for that like function ArCoreNode for shape..
how can improve or add new function to plugin ......

Hello,

Is possible to render a video with transparent background in a fixed position with the plugin?

Thank you!

Is possible to change the ARFaceModel at runtime? I didn't make it work, the texture remains always the same. Seems that a new call to arCoreFaceController.loadMesh doesn't load the new texture.

Used the example code mentioned in https://pub.dartlang.org/packages/arcore_flutter_plugin#example

Is it possible to detect a tap on nodes of my own ArCoreReferenceNode?

Hi, in the remote object feature, the official documentation says that you can load either a GLTF or GLB file.

But in the plugin trying a link with a GLB at objectUrl in ArCoreReferenceNode it seems not to be working.

Any updates on that will be really helpful

Hi!

First of all great job for your plugin it's work perfectly even on emulator!

Thanks to Oleksandr Leuschenko I have measure feature in AR on iPhone.
So I would like to know if you can add measure feature in your plugin.

Thank you in advance!
