Not able to see the glb file

[Gaurew]

I used the plugin . Made changes in build.gradle. Permissions etc.
I am using flutter 3.29.0. The new version of flutter didn't cause any complicated issue to me. The build was smooth.
However when running the app . I was not able to see the object which i wanted to see.
I downloaded a dog glb file. And saved it into my assets folder.
Gave paths and everything .

I have uploaded the project on my github . Please review it . Your help would be appreciated.

I am finding the same issue, did you test on iOS? For me on iOS the sample scene here https://github.com/hlefe/ar_flutter_plugin_2/blob/main/examples/local_and_web_objects.dart loads local objects and file system objects fine but on android devices the models don't load from local file system paths they only load from the web on android. Any local file system saved glb doesn't seem to load including the LocalDuck.glb which I have also tested with File.Exists to see if it exists and it does:, in the below log I check a model I am trying to load exists and it does but then I get a FileNotFoundException:

I/flutter (27064): File exists: /data/user/0/com.epm.pi.epm_pi_test/app_flutter/website/models/DamagedHelmet.glb

W/System.err(27064): java.io.FileNotFoundException: /data/user/0/com.epm.pi.epm_pi_test/app_flutter/website/models/DamagedHelmet.glb

Hi @ROBYER1

1. In pubspec.yaml, make sure you have added the folder containing your models.

Example

The .glb file is located in the assets/models folder:

pubspec.yaml

  assets:
    - assets/models/

2. Use NodeType.localGLTF2 even if it is a .glb file:

var newNode = ARNode(
          type: NodeType.localGLTF2,
          uri: "assets/models/Duck.glb",
          scale: Vector3(0.2, 0.2, 0.2),
          position: Vector3(0.0, 0.0, 0.0),
          rotation: Vector4(1.0, 0.0, 0.0, 0.0)
);

@Gaurew
On your side, the issues are as follows:

1. The scale you defined was too large:
   Replace scale: vm.Vector3(10,10,10), by scale: vm.Vector3(1, 1, 1),
2. Regarding the position, it is relative to the hit location, so you should set it to 0,0,0 if you want the object to appear where it was tapped:
   Replace plane.worldTransform.getTranslation(), by position: vm.Vector3(0, 0, 0),
3. I also made an adjustment to the rotation:
   Replace rotation: vm.Vector4(0.0, 0.0, 0.0, 1.0), by rotation: vm.Vector4(1.0, 0.0, 0.0, 1.0),
4. Finally (and most importantly), you need to first create an anchor at the hit location:

final singleHitTestResult = hitTestResults.first;
var newAnchor = ARPlaneAnchor(transformation: singleHitTestResult.worldTransform);

Then specify the anchor when adding the node:
Replace arObjectManager.addNode(node) by arObjectManager.addNode(node, planeAnchor:newAnchor)
