flutter sharedmem_gpumem_alloc:

使用cached_network_image加载网络图片时，遇到sharedmem_gpumem_alloc: mmap failed errno 12 Out of memory，然后app会闪退。
解决办法，设置缓存图片的宽高，如下：

CachedNetworkImage(
                  imageUrl: imageURL,
                  placeholder: (context, url) => CircularProgressIndicator(
                    valueColor: AlwaysStoppedAnimation<Color>(widget.navColor),
                    strokeWidth: 1,
                  ),
                  errorWidget: (context, url, error) => Icon(Icons.error),
                  memCacheWidth: 180,
                  memCacheHeight: 180,
                  width: 180,
                  height: 180,
                  fit: BoxFit.cover,
                ),

Have fun.
