为什么我获取图片的时候利用Image.network之后会报这种错误：
Another exception was thrown: SocketException: Failed host lookup: ‘dimg04.c-ctrip.com’ (OS Error: No address associated with ho
stname, errno = 7)
图片描述 swiper是这么写的：

List _imageUrls = [
  'http://pages.ctrip.com/commerce/promote/20180718/yxzy/img/640sygd.jpg',
  'http://dimg04.c-ctrip.com/images/700u0r000000gxvb93E54_810_235_85.jpg',
  'http://dimg04.c-ctrip.com/images/700c10000000pdili7D8B_780_235_57.jpg'
];
child: Swiper(
  itemCount: _imageUrls.length,
  autoplay: true,
  itemBuilder: (BuildContext context, int index) {
    return Image.network(
      _imageUrls[index],
      fit: BoxFit.fill,
    );
  },
  pagination: SwiperPagination(),
),
