Items flickering on scroll, use SliverAppBar with scrolledUnderElevation instead

[maherjaafar]

You can use SliverAppBar with scrolledUnderElevation instead of this package.

Example code:

  CustomScrollView(
      slivers: [
        const SliverAppBar(
          title: Text('Dynamic elevation'),
          pinned: true,
          scrolledUnderElevation: 20,
        ),
        SliverList(
          delegate: SliverChildBuilderDelegate(
            (_, int index) {
              return ListTile(
                title: Text(index.toString()),
              );
            },
            childCount: 20,
          ),
        ),
      ],
    );
