we just migrated from zsoltk/compose-router to navigation-compose and a few issues rose to the forefront:
• when where there be support for animation transitions between screens?
• is there anyway to create a nested graph?
• has anyone noticed sluggish performance when navigating? tapping a BottomNavigationItem used to have a clean ripple effect when navigating, and now it's super choppy (even without any screen to screen transition)

• Animations are not supported yet, please star https://issuetracker.google.com/issues/172112072
• alpha02 will allow you to associate a route with a nested graph: https://android-review.googlesource.com/c/platform/frameworks/support/+/1483385 but it is
• We haven't seen this, so please file a bug

i don't think I can access that issue, my google username/pw doesn't work either

[Ian Lake]

Should be the issuetracker link, try the updated one ^

[Sam]

There was a long thread about transitions that might be good reading: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1604093221008800

[Sam]

very helpful thread! when it comes to specific transitions, we are coming from iOS and so these are the ones im most interested:

[Sam]

I was already able to achieve the modal by using ModalBottomSheetLayout although i kinda hacked it separate from navigation

[Sam]

i haven't achieved the push slide, as it coordinates the new screen moving in tandem with the current screen. are these common to android in general?
