【flutter】两个Container之间会出现一条线

这个问题为flutter上的bug,目前为止3.16.4还未修复
解决办法：为Container设置宽度为0颜色为填充色的Border

Container(
      color: Colors.black,
      child: Column(
        children: [
          Container(
            height: 31,
            decoration: BoxDecoration(
              border: Border.all(color: Colors.white, width: 0),
              color: Colors.white,
            ),
          ),
          Container(
            height: 31,
            decoration: BoxDecoration(
              border: Border.all(color: Colors.white, width: 0),
              color: Colors.white,
            ),
          ),
          Container(
            height: 31,
            decoration: BoxDecoration(
              border: Border.all(color: Colors.white, width: 0),
              color: Colors.white,
            ),
          ),
        ],
      ),
    )
