Repository navigation
Hero Widget transitionOnUserGestures animates wrong. #32356
Description
Steps to Reproduce
- Run this main.dart file
https://gist.github.com/skabber/8dbf7cdee1431b13d8b87d8ff9075fa3
When a Hero widget with transitionOnUserGestures set to true navigates back using the gesture, the animation shrinks too small and closes out entirely before it's final state.
I would expect the animation to only go as small as the final resting place.

Yeah sorry I didn't realize it only happens when you navigate back using gesture.
LongCatIsLooong commentedon May 10, 2019
OK this happens on asset images too.

Thanks @LongCatIsLooong
Adding the height in does correctly work around the issue.
