Inner drawer with sliver

[uvlek]

Please help me to deal with this issue. When I use inner drawer with sliverlist - error happens

Code:

import 'package:flutter_inner_drawer/inner_drawer.dart';

class WhiteLayout extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return InnerDrawer(
      leftChild: Container(),
      rightChild: Container(),
      scaffold: Scaffold(
        body: CustomScrollView(
          slivers: <Widget>[
            SliverAppBar(
              expandedHeight: 200.0,
              flexibleSpace: const FlexibleSpaceBar(
                title: Text('Available seats'),
              ),
              actions: <Widget>[
                IconButton(
                  icon: const Icon(Icons.add_circle),
                  tooltip: 'Add new entry',
                  onPressed: () {},
                ),
              ],
            ),
            SliverToBoxAdapter(
              child: SizedBox(
                height: 600,
                child: Center(
                  child: Text('Main content here'),
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }
}
