以离线添加dio包为例阐述如何解决该问题。
1、到 https://pub.flutter-io.cn/packages/dio/versions 去下载最新版本的dio.dart库文件，下载下来是一个dio-3.0.8.tar.gz文件；
2、将dio-3.0.8.tar.gz文件解压到dio-3.0.8目录下；
3、将dio-3.0.8文件夹整个拷贝到 flutter/.pub_cache/hosted/pub.flutter-io.cn/ 目录下；
4、打开flutter项目根路径下的 .packages 文件，在里面最后一行添加dio lib的路径。如： dio:file:///D:/flutter/.pub-cache/hosted/pub.flutter-io.cn/dio-3.0.8/lib/
5、在main.dart文件中即可 import 'package:dio/dio.dart'; 了
