Present modally in Flutter? : <p>How to do a modal presentation of a route in Flutter?</p>

<p>I figured out how to navigate to a route using the usual "push" transition, but I am struggling to implement a modal transition. See animation attached (done using native iOS). How do I present a screen modally (a screen that itself can be pushed more screens to).</p>

<p>See an example below. The transition I am struggling with is from "A" to "C" (and of course a way to dismiss it and go back to "A").</p>
