I'm looking for half modal that I can operate the back page

Issue

I'm looking for half modal that I can operate the back page.
(It's like when I tap a pin on Google Maps.)

I used showModalBottomSheet, but I can't operate the back page.
I searched for an option that would meet my request, but it didn't exist.

Is there any way?

Solution

I self-solved.

I use showBottomSheet, not showModalBottomSheet.
