animation/secondaryAnimation transition delegates #210

Closed lukepighetti closed 3 years ago

lukepighetti commented 3 years ago

Any page should be able to have a transition for when it is presented/dismissed, or when it is covered/revealed (a page is presented on top of it).

Flutter semantics for this is animation and secondaryAnimation.

Tracking this for Nav 2.0 rewrite

Page A secondaryAnimation should be visually paired with Page B animation. This is what makes iOS routing so dynamic and compelling.

In other words, a Page's true secondaryAnimation should be pulled from the page that is being pushed over it, as that will match the motion of the push animation.
