I want to use this animation for Bottom Navigation on Flutter, but I don't know what to do.
There are a total of 5 tabs including the button with that animation applied.
Animation button is centered.
Help me, masters.
Floating buttons should not be used...
Let's say I have a fade through transition going into another page, and then when I want to go back, it uses the same fade through transition but reversed.
How do I make it so that the animation is different upon the reversed animation?
I am looking forward to creating a similar animation in the ModalBottomSheet, shown in the below image. The animation in the above bottom navigation bar Is there any idea how to achieve it?
I have a canvas with an animator that animates the transition between different menu items. I also have buttons (nested in canvas) whose position and size are animated by canvas. And each button has its own animator with the animation "pressed" (resizing and rotation). The problem is that the button click animation has the wrong look. The button does not change its size and rotates a smaller degree. I think the point is in the "weight" of the animation, since canvas animates the same button. But I have no idea how to fix it ...

Is it possible do something like this ?
When I click on the button I need the following animation: button to set some alpha filter and starts to fall down as indicated by the arrow, it will disappear on tab.
Can you tell me how to do this ? Thanks a lot ...

It's definitely possible, but there are some issues you have to overcome. One is that UIBarButtonItem isn't a UIView. One way is to loop through the subviews of the UIToolbar or UINavigationBar. Another way is to figure out the position of the button. Another is to get the view using private api if you're not submitting to the AppStore.
Once you have the view, you can move it to the superview of the UIToolbar or UINavigationBar or you can create a view on top of that (and hide the real UIBarButtonItem since you're done with that). The latter is more difficult because mimicking the look of the default bordered UIBarButtonItem isn't easy.
Now you need to get the center of the UITabBarItem somehow. You can either use private api or you can loop through the subviews.
Create a CGPath using Quartz functions or using UIBezierPath. The start point will be the center of the button and the end point will be the center of the UITabBarItem.
Create a CAKeyFrameAnimation and attach said CGPath.
Create a CABasicAnimation to animate the opacity.
Add both to a CAAnimationGroup.
Attach the animation group to your button view's CALayer.
Make sure to also set the position and the alpha in order to prevent the view from jumping back to its original position after the animation.
Once you attach the animation group, the animation should start, so make sure you're doing all of this in the button's selector method.
You can't really move it from view to view, as your views could clip and then you'd get frames with only a partial image. Probably the best thing to do is to create a view on the fly which covers the whole screen, copy the button image into the view at the original point, remove the button from the original view, then animate that image to where you want it to go, then add the button to the final destination.
