What is the current behavior?

Swipe back on iOS immediately triggers back navigation, rather than showing a native-like transition.

Issue URL: #22342

What is the new behavior?

Swipe-back in ios mode performs a smooth swipe transition animation, then triggers back navigation at the end of the transition (if the swipe went far enough).

Does this introduce a breaking change?

• Yes
• No

Hey there,

Thanks for the PR! We really appreciate all the hard work you put into creating this. I put up a new PR in #25563 that is a combination of your work and my work. I also added some tests so this behavior does not regress.

I am going to close this in favor of the new PR, but I will be sure to give you co-author credit if the PR merges. Also, there is a dev build in #22342 (comment) if you are interested in testing this fix out in your apps. Thanks again!
