There is an field in ListView physics = NeverScrollableScrollPhysics(); Now you can implement it base on some condition – Griner

Can you talk more about what you've tried and what didn't work? – Transubstantiation

Answer 1

As mentioned in the comments, the NeverScrollableScrollPhysics class will do this:

NeverScrollableScrollPhysics class

Scroll physics that does not allow the user to scroll.

Answer 2

Inside ListView widget, use

physics: const NeverScrollableScrollPhysics()

Answer 3

You may add just primary: false inside your ListView Widget

Defaults to matching platform conventions. Furthermore, if the primary is false, then the user cannot scroll if there is insufficient content to scroll, while if the primary is true, they can always attempt to scroll.

Answer 6

what about NestedScrollView ?

            bottomNavigationBar: _buildBottomAppBar(),
            body: Container(
              child: NestedScrollView(
                physics: NeverScrollableScrollPhysics(),
                controller: _scrollViewController,
                headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
                  return <Widget>[
                    buildSliverAppBar(innerBoxIsScrolled),
                  ];
                },
                body: _buildBody(context),
              ),
            ),
          );

it's working for me
