Configuring pub environment variables

Environment variables allow you to customize pub to suit your needs.

PUB_CACHE

Some of pub's dependencies are downloaded to the pub cache. By default, this directory is located under $HOME/.pub-cache (on macOS and Linux), or in %LOCALAPPDATA%\Pub\Cache (on Windows). (The precise location of the cache may vary depending on the Windows version.) You can use the PUB_CACHE environment variable to specify another location. For more information, see The system package cache.

PUB_HOSTED_URL

Pub downloads dependencies from the pub.dev site. To specify the location of a particular mirror server, use the PUB_HOSTED_URL environment variable. For example:

PUB_HOSTED_URL = https://pub.example.com
