[animations] SharedAxisTransition resets ongoing animations after SharedAxisTransition page transition is complete #55826
Description
Hi. Thanks for the animations package. I've found unexpected renders in shared axis transition.
While moving forward it makes 3 component renders and only one while going back.
Here is how it look in while logging https://tppr.me/KSBAK
The logs are based on the bundled example.
Is this ok behaviour or we can somehow omit the additional _CoursePage build?

Hi @vasilich6107
As far i know, builder function being multiple times is perfectly normal. It's just trying to stay updated
You can try in separate, it will have same behaviour
Please see https://flutter.dev/community for resources and asking questions like this, you may also get some help if you post it on Stack Overflow.
Closing, as this isn't an issue with Flutter itself,
if you disagree please write in the comments and I will reopen it
Thank you

If I have something on the second card which I show with SharesAxisTransition it will render twice.
It could result in two network requests, jiggling spinner(restarts from initial animation on each rerender...)
I'm just trying to understand is this a bug in
animations(https://pub.dev/packages/animations) library or this is ok behaviour...vasilich6107 commentedon Apr 28, 2020
I made this video to illustrate what I'm talking about.
In this extra slow-motion you can definitely see how spinners on courses list after making almost full circle just reseted to the initial animation. This is caused by the second in a row animation illustrated here https://tppr.me/KSBAK

May be the authors(@shihaohong, @goderbauer) of that transition could comment on this issue?
