Hi, Suresh.

This mailing list is focused on people working on or contributing to evolving the Dart language itself. I think you'll have better luck on the flutter-dev list (which I see you've posted this at too). Good luck! :)

First time working on perspective projection related app using flutter. Where I need to show 3D point over camera view in 2D. I have a couple of questions regarding this...

1. How to convert any 3D point to 2D using Dart. Can vector_math package do any help? An example will be a great help.
2. when user will move the camera to a certain direction, how can I fig. out what's are those 3D points come inside my camera field of view?
3. In flutter how to place something over camera view at a certain position using 2D points? Can I use flutter canvas class for that or something else? Because I've seen some sample code at where you can draw or paint certain object using canvas class.
   

It'll be a great help if anyone give some guidance.
