如何将自定义子滚动视图 silverlist 中的元素居中？

return CustomScrollView(
  physics: BouncingScrollPhysics(),
  slivers: <Widget>[
    SliverList(
        delegate: SliverChildListDelegate([
      SizedBox(height: widget.height),

      HeaderTitle("Hello there"),
      (data.length == 0)
          ? Center(
              child: Container(
                // padding: EdgeInsets.fromLTRB(0, 150, 0, 0),
                child: Column(
                  children: [
                    Text("No Data Yet"),
                    OutlineButton(
                      onPressed: () {
                        Navigator.of(context).pop();
                      },
                      textColor: Colors.black,
                      child: Text("Do Something"),
                    ),
                  ],
                ),
              ),
            )
          : Container()
    ])),
  
    SliverGrid(
      gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
        childAspectRatio: 10.0 / 10.0,
        crossAxisCount: 2,
      ),
      delegate:
          SliverChildBuilderDelegate((BuildContext context, int index) {
        return CastCard(data[index], null);
      }, childCount: data.length),
    ),
  ],
); …
