Can I add 3d object in Flutter and then edit that by creating 2d circles on the object in certain points? If yes then how.

I'm a beginner with Unity. I want to drag a 2D image from my inventory and drop it in the scene as a 3D object. I can already drag and drop the 2D image in the scene. Can anyone help me please?
You will have to use ScreenToWorldPoint to map the 2d input to 3d coordinates then instantiate your 3d object.
I try build app on Kudan platform. I am using Unity 3d and the last version of Kudan SDK. I used Marker tracking but I don't how to set correct position to 3d model which I want to show on marker. When I build app and use marker for show 3d model. 3d model is still moves and floats above or below the marker. Is it possible set marker and 3d model in Unity to the same level? Is is possible show marker in Unity scene-mode?
Can the 3D models used with the markers be made clickable and rotate able using Unity3D engine and ARToolkit unity. Basically in the AR desktop application we are making , we want to implement this functionality on the 3D models as well. Kindly need help in this matter. ThankYou.
The only issue you could find is that the Transformation of the AR Tracked Object changes based on the visual information.
If you simply use that as a base object and put any other models as children of that one, you can modify their position and rotation in the same way you would do for any other situation.
So, as you see, the Marker scene has nothing but an AR Tracked Object, this is the object that will be updated with the pose of the marker.
Then, the Cube is a child of this object. If you modify the localPosition or localRotation of the cube it will work as you want it.
The Cube is a child of the Marker scene, its global position and rotation will be a combination of the position and rotation of its parent with its local position and rotation (this is standard 3DEngine / SceneGraph behaviour).
There's plenty of tutorials which explain how to add and manage image objects. But what if I want to add simple rectangle with plain white color? May I do it similar to adding 3D objects? I see no rectangle option under 2D Object in GameObject menu.
I know that I may do it by script, but isn't there any simpler solution? Or maybe I should use 3D Object Cube instead?
For a rectangle (ie a 2D cuboid) you add a 3D object that is a Quad which is a 3D object with a size of 0 in one plane, in effect making it a 2D sheet.

Quads are most often used as backdrops to 2D games. Once you have the quad you can then change its material properties to set it as a single plain colour.
I am new to develop augmented reality apps. I have followed some tutorial to show 3D model using unity 3D and vuforia and it works fine. Now I need to show 2D image instead of 3D model
As suggested by Bart in the comments. Go ahead and put in a plane. On the plane add a Texture that has the picture of the image you want to see.
FYI: Augmented Reality is for the eyes to view a 3D image. Else we'd
just be using an app on screen.
