颤振：如何为 sliverlist 设置背景

Question

I've develop an app.There is a page like this:

If there are more comments, the picture and comment list can be scroll.So I put them in a CustomScrollView.The question is how can I set background for the SliverList?

Answer 1

Add a grouping background by customizing the RenderSliver.: https://github.com/mrdaios/flutter_group_sliver

flutter_group_sliver: ^0.0.2

Answer 2

You can wrap the 'CustomScrollView' on a Container, and set a color for that Container. This is how I solved:

Widget build(BuildContext context) {
    return Container(
      color: Colors.white,
      child: CustomScrollView(
        slivers: <Widget>[
          SliverAppBar(
            title: Text('Title'),
            expandedHeight: 100.0,
            flexibleSpace: FlexibleSpaceBar(),
          ),
          SliverList(
            delegate: SliverChildListDelegate([]),
          )
        ],
      ),
    );
  }

Answer 3

尝试在 Container 中包装 CustomScrollView 并为容器小部件提供颜色。
