Listview抖动中项目之间的不必要间隙

Question

我有一个Listview，其内容是动态的。 Listview用于显示动态窗口小部件的列表。 使用以下代码填充Listview

new Container(
      color: Colors.white,
      child:
      new ListView(
        padding: EdgeInsets.all(0.0),
        children: _widgetsList.map((Widget item){
          return new Container(
            color: Colors.red,
            child: item,
          );
        }).toList(),
      ),
);

输出是下面的图像

问题是列表视图中的每个项目之间都出现了很小的间隙，我希望将其删除。

等待您的帮助！
