Incorrect Rotation of ARKit Nodes in ARKitPlugin for Flutter

[EdgarAldair]

When scanning images using ARKitSceneView, the added ARKit nodes rotate unpredictably on the X and Y axes. Sometimes they appear correctly, but other times they rotate by 90°, 10°, etc.
basically the image orientation flips when scanning from different angles when the camera initialize

Steps to Reproduce

1. Set up ARKitSceneView with image detection group 'AR Resources'.
2. Add an ARKitNode with specific eulerAngles or orientation.
3. Observe the node's rotation during and after image detection.

Expected Behavior

ARKit nodes should maintain a consistent and correct orientation without random rotations.

Actual Behavior

Nodes rotate inconsistently:

• Sometimes by 90° on the X-axis.
• Other times by 10° on the X-axis.
• Every time it is different

Code Snippet

final node = ARKitNode(
  scale: vector.Vector3(0.1, 0.1, 0.1),
  geometry: plane,
  position: vector.Vector3(
    earthPosition.x,
    earthPosition.y,
    earthPosition.z,
  ),
   eulerAngles: vector.Vector3.zero(),    // Attempted rotation
);

It would help to see the code you are using to add the node to the scene. All of the values of the node are relative to the parent. If there is no parent then they are relative to the world origin which is dependent on your configuration. This includes the rotation values. If you want the node to be relative to something in the real world then you'll need an anchor of some sort. It also helps to set your configuration so that you get some definition of direction. Here's what I do:

ARKitSceneView(
      configuration: ARKitConfiguration.worldTracking,
      showFeaturePoints: false,
      showStatistics: false,
      planeDetection: ARPlaneDetection.horizontal,
      worldAlignment: ARWorldAlignment.gravityAndHeading,
      onARKitViewCreated: onARKitViewCreated,
      showWorldOrigin: false);

This does. a few things:

• Sets the configuration to world tracking instead of relative to the camera
• Sets up to detect horizontal planes, tables, floors, etc
• Sets the coordinate system to be gravity and heading, that is Y axis is aligned with gravity and X and Z are aligned with the compass. See here: https://developer.apple.com/documentation/arkit/arconfiguration/worldalignment-swift.enum/gravityandheading
• The world origin is the device

In the onARKitViewCreated method I register my callbacks for when the plane anchors are found. Anything you want to be stable should be a child of the plane anchor.
