How to pop up a popMenu for the onLongPress of a DataRow in a DataTable

I am new to learning Flutter and I am really inspired by the “!Not Boring Calculator” app (if you haven’t checked out the app, please do – it’s really good). In this app, there is a 3D number effect which I am trying to recreate. I know there’s a lot going on behind the scenes, but I want to create a similar-ish type of effect. Do you have any suggestions on how I can do that?

how can I rotate the white ball inside the circle after the animation has drawn? Now in order for the first animation to work, I need to pass the tween to the animation, but for the rotation to work, I need to attach a listener to the controller. How to combine these two options? I need the first gradient animation to fire first and then be able to rotate the ball inside the circle. I understand that this requires a gesture detector which I use, but how to properly combine both animations

So, what i want to achieve it one AnimationController with multiple animation, and i want to reverse specific animation in that controller, right now i am using multiple controller each as parent of single animation
