CachedNetworkImage ..引发HandshakeExceptionCERTIFICATE_VERIFY_FAILED

问题描述

每当我调用CachedNetworkImage并将URL放入imageUrl时，都会从Web服务器获取图片时出现的错误使我感到惊讶，

CacheManager: 
Failed to download a file from(URL...)
HandshakeException: Handshake error in client (OS Error: 
I/flutter (20243):      CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:354))

ps：暂时不要介意我的getData函数（），我只想显示一张图像，该图像与另一个小部件的参数一起传递
