> The Transition Kotlin extensions target the Framework Transition class which is a bit confusing
All extensions in 'core-ktx' target either 'core' or the framework types. This is working as expected. It sounds like this is a feature request for a transition-ktx with equivalent extensions for the androidx.transition types.
> as most framework classes are being deprecated in favor of their AndroidX counterparts, Fragments for example.
"Most"? This *dramatically* overstates what is actually happening. Fragments (and loaders) were added to the framework in a time where the Android team did not have external libraries for shipping features. Transition was added 5 years later.

Pardon my misunderstanding, I was under the belief that where possible, new features that could be developed outside the framework, would be under Androidx. Also it's a common refrain to use the Androidx libraries over the framework libraries where possible, as those ship update independently of platform releases. I wasn't attempting to be dramatic.
If the Transition api is unlikely to change, there is no need for a transition-ktx for androidx.transition types. If developers should use Androidx transitions over framework transitions where possible however, then it would be much appreciated.
I am well aware of the limitations that existed when Fragments and Loaders were created, and when the Transition api was introduced.

Introduce transition-ktx for standalone transition library
These extensions are the same as androidx.core.transition for the platform types, just adapted to the standalone library.

Fixed in 1.1.0-alpha02 version of Transition lib.
Description
'com.android.support:appcompat-v7:28.0.0'
'com.android.support:design:28.0.0'
Version used: 28.0.0
Theme used: Theme.AppCompat.Light.DarkActionBar
Devices/Android versions reproduced on: Nexus 6 running API 27
If we set a Propagation (Tested only for SidePropagation) on a support transition which has a start delay, then the propagation isn't respected when animating the views out (but is when animating the views in).This is in contrast to the native implementation of this feature, where it works correctly when animating in, or out with a start delay.
- Relevant code to trigger the issue.
//support transitions
android.support.transition.SidePropagation propagation = new android.support.transition.SidePropagation();
propagation.setSide(Gravity.END);
android.support.transition.Transition propagatedTransition = new android.support.transition.AutoTransition();
//Using a start delay causes the support version to not propagate the transition when animating out
propagatedTransition.setStartDelay(150);
propagatedTransition.setPropagation(propagation);
android.support.transition.TransitionManager.beginDelayedTransition(rootViewGroup, propagatedTransition);
toggleChildren(supportLayout);
- A screenrecord or screenshots showing the issue (if UI related).
Attached is a screen record of it. I've also attached a sample project. Simply tap the green (native - working) box to trigger the transition using the native Transition API, and the red (support - broken) box to trigger the transition using the support Transition API. You may want to make the transition longer and change the propagation speed to make it more obvious (e.g. 0.1f propagation speed)
