The pub.dev server or a custom package repository is unreachable due to network issues, firewall blocking, or DNS resolution failure.

由于网络问题、防火墙阻止或 DNS 解析失败，pub.dev 服务器或自定义包仓库无法访问。

85% success Check network connectivity and ensure pub.dev is accessible. Temporarily disable VPN or firewall, then run 'flutter pub get --offline' if dependencies are already cached, or use a mirror like 'dart pub get --no-precompile' with PUB_HOSTED_URL set to a mirror.

检查网络连接并确保 pub.dev 可访问。临时禁用 VPN 或防火墙，然后运行 'flutter pub get --offline'（如果依赖已缓存），或使用镜像，设置 PUB_HOSTED_URL 为镜像地址。

使用不同的 DNS 服务器（例如 Google DNS 8.8.8.8）或在防火墙/代理设置中添加 pub.dev 的例外。

Common approaches that don't work:

Repeatedly running 'flutter pub get' without any network changes 95% fail
The underlying network issue persists; retrying does not resolve connectivity problems.
Deleting the pubspec.lock file and running pub get again 85% fail
The lock file is not the cause; the error is network-related, so deletion has no effect.
