Create a Flutter transition animation

I have a Flutter app with a list of tiles which contain an image and title and when tapped they open a new screen with the image and title at the top and a page of content. I want this to be animated so that the list item itself expands to fill the screen and the image and title move into place while the page content comes into view. I would need the PageRouteBuilder and animation created in Flutter.

Any questions please ask.
