Usage & Overview

To start using Hidable widget, we have to create a ScrollController. inctance before.

final ScrollController scrollController = ScrollController();

As case of usage, we should have one scrollable widget (SingleChildScrollView, ListView etc) and one static located widget (AppBar, BottomNavBar etc) which'd be wrapped with Hidable widget.

So, scrollController which we created before must be given to each one (scrollable widget and static located hidable widget).

Scrollable widget

ListView.separated(
  // General scroll controller which makes bridge between
  // This ListView and Hidable widget.
  controller: scrollController,
  itemCount: colors.length,
  itemBuilder: (_, i) => Container(
     height: 50,
     color: colors[i].withOpacity(.6),
  ),
  separatorBuilder: (_, __) => const SizedBox(height: 10),
),

Static located hidable widget

Hidable(
  controller: scrollController,
  wOpacity: true, // As default it's true.
  size: 56, // As default it's 56.
  child: BottomNavigationBar(...),
),

That is the common usage of hidable, and also you can find full code implmenetation of hidable at official example page.

More than one Hidable widget on the same screen

My page design calls for two widgets which need hiding when the list is scrolled, one at the top and one at the bottom. If I create two Hidable widgets in one class, it doesn't seem possible to set the size correctly. Whatever size value I give the top Hidable, it seems to apply this also to the bottom one, regardless of the value I set there.

Is there a workaround for this, or any suggestion as to how I might implement this?

Cannot use Hidable as an AppBar

Scaffold's appbar: field requires a PreferredSizeWidget and not normal Widget. That's why we cannot use Hidable as a wrapper of AppBar. We should a factory builder -> (Hidable.preferredSizeWidget() or Hidable.appbar()) or another widget that returns PreferredSizeWidget instead of normal Widget.

Widget has its own background

The Hidable has its own background, with elevation and background color, probably it takes the material common color of theme, so, in my case white.

In any case we should remove the Material widget from under the Hidable. Otherwise there is no way to avoid this issue:

The white parts (on top-left and top-right) is Hidable's background, which actually should be transparent.
