I want a package to display a 3D object with the event of pressing the object, where it applies a function when the user clicks on the object.
I used the flutter_cube package but it doesn't have events

Can I build 3D (OpenGL) apps with Flutter?
Today we don’t support for 3D via OpenGL ES or similar. We have long-term plans to expose an optimized 3D API, but right now we’re focused on 2D.

I have seen this video: https://youtu.be/v9M2Ho9I9Qo?t=49
It’s about creating AI for “GO”
at 0:50 he talks about feeding a neural network a game state of go and a possible move of a player.
My question: what are the best way to feed the game state and the move. I know I can just feed the neural net all the game states after each possible move. But in the video, he said he feeds the move with the board state before the move.
how should it be done?
I think you need to understand policy-based methods. In policy-based methods we are trying to learn directly the policy function that maps state to action.(policy gradients and actor-critic method)

I want to display a 3D model in my application (whose file format is .obj) on my page. The user can rotate this model, like iOS's SceneKit, but I don't have any idea for this. Can anyone help me with how to handle 3D objects in flutter?

you can check out this repo, but the performance is not really good. I think you can consider using texture to implement.

I'm a unity3d beginner and I have a problem about attaching a gun to my T-Pose character. Please answer how can I attach the gun to my t-pose character and use the gun in-game with seeing my character's hands.
Depends.
If you're using code, or an engine like UFPS, then you'd attach it with a gameobject.
If you want it to be part of the model/animation, you have to either acquire a model that has that already, or model it yourself.
I'd recommend that you search Google for it though, since it's more likely to have better answers for you.

I want to make a simple 2D card game. The game should be multiplayer and lan based. That is user can play the game on lan. Besides they should be able to commuinicate via headphone. So is there any help from unity side for this type of lan game making. If yes from where can i learn ?
Unity3D has networking capabilities for multiplayer games. However I don't think that it supports teamspeak like communication but there are third party libraries for that I suppose. For learning resources it is right here http://docs.unity3d.com/Documentation/Manual/index.html

I am developing an application that is heart rate app.
I would like to dislay heart rate in Chart view.
Could you tell me how to implement it or there is any chart framework for this case?
Please give me advise!
Using CorePlot framework is little bit complicated, but its good.
Otherwise if you need very simple Graph then go for ECGraph
Use CorePlot for that, I've used it in the past and it was great:
