如何在widget的listview中以编程方式设置项目的背景色？

ListView.builder(
  itemCount: data.length,
  itemBuilder: (BuildContext context, int index) {
    return Container(
      color: Colors.blue, // 设置背景色
      child: ListTile(
        title: Text(data[index]),
      ),
    );
  },
)

ListView.separated(
  itemCount: data.length,
  separatorBuilder: (BuildContext context, int index) => Divider(),
  itemBuilder: (BuildContext context, int index) {
    return Container(
      color: Colors.blue, // 设置背景色
      child: ListTile(
        title: Text(data[index]),
      ),
    );
  },
)
