FlutterでListView.builderを複数使う方法

body: CustomScrollView(
        slivers: [
          SliverList(
            delegate: SliverChildListDelegate(
              [
                const Text('Header'),
                const Divider(),
              ],
            ),
          ),
          SliverList(
            delegate: SliverChildBuilderDelegate(
              (context, index) {
                return Text(state.listA[index]);
              },
              childCount: state.listA.length,
            ),
          ),
          SliverList(
            delegate: SliverChildBuilderDelegate(
              (context, index) {
                return Text(state.listB[index]);
              },
              childCount: state.listB.length,
            ),
          ),
