Hideable Widget

First, create a scroll controller.

final scrollController = ScrollController();

Immediately afterwards, give this scroll controller to your scrollable widget.

ListView(
    controller: scrollController,
    physics: const ClampingScrollPhysics(),
    children: [
        ...List.generate(
        50,
        (index) => ListTile(
            title: Text("List item ${index + 1}"),
        ),
        ).toList(),
        const SizedBox(height: 100),
    ],
),

After wrapping your static widget with the hideable widget, give the hideable widget this scroll controller.

HideableWidget(
    scrollController: scrollController,
    child: BottomAppBar(...)
),

That's all. Now you are ready to use the hideable widget.

Parameters are as follows. ☺️

• child: This is the static widget you want to hide while scrolling.

• scrollController: It should be the same as the scroll controller supplied with your scrollable widget.

• useOpacity: Used to turn the opacity animation on and off. It is on by default.

• duration: Use this to set the hiding time.

• opacityDuration: Use this to set the opacity duration that runs during the hiding period.
