How to tap inset to dismiss and tap region to expand?

[RoyGuanyu]

Is it possible to

1. dismiss by tapping the top inset
2. enlarge(expand) the card by tapping the card

using ModalExprollableRouteBuilder.

Navigator.of(context).push( ModalExprollableRouteBuilder( pageBuilder: (context, _, __) => ExprollablePageView(...), ), );

I try to set barrierDismissible to true, but not working. ModalExprollableRouteBuilder( barrierDismissible: true, pageBuilder: (context, _, __) => const CustomView(),),

Thanks.

You can use ExprollablePageController. animateViewportInsetTo to enlarge your card with animation. An example code is available here.

I try to set barrierDismissible to true, but not working.

Can you post a minimal code to reproduce your problem? Since barrierDismissible is enabled by default, the dialog should close if you touch the barrier without explicitly setting it to true.
