Old screen transitions are used on Android API 28

[noelmansour]

Here's what a slowed down version of an activity transition looks like on Android API 27. It's a slide up + fade in animation:

After #13736 is fixed (or using MaterialPageRoute.debugEnableFadingRoutes = true), this should match Flutter's current behavior.

However, API 28 uses a different transition. It's a reveal + more subtle slide up animation:

MaterialPageRoute should use a transition that is consistent with the API level.

@zeochi: thanks for the reminder. Support for Android P transitions was added in #21715.
