How to close expanded body on main body tap?

[nidhi1612]

Hello,

I am new to flutter. I have used expanded bottom app bar, i want to close the expanded body when user taps in the outside area. However i dont know how it can be done.

What exactly should be detected in order to close the pulled up expanded bottom bar?

You could add a GestureRecognizer to the outside area, and call close on your BottomBarController, for example:

DefaultBottomBarController(
  child: Scaffold(
    body: GestureDetector(
      onTap: DefaultBottomBarController.of(context).close,
      ... 
    ),
    bottomNavigationBar: BottomExpandableAppBar(
    ... 
    ),
  ),
);
