pub uses %APPDATA% and not %LOCALAPPDATA%

What steps will reproduce the problem?

1. Check pub's cache dir on Windows OR
2. Check pub global's exes dir on Windows

What is the expected output? What do you see instead?

Stuff is stored in %USERPROFILE%\AppData\Roaming...

i. e.

%APPDATA%...

Because pub does not store configuration data, but cached data and scripts, it seems strange that pub stores stuff in the roaming profile, as Dart many not be installed on other computers the user accesses. It seems more adequate to store the cache and pub global exes in the %LOCALAPPDATA% folder.

Note that if config data was stored instead, it would be more justifiable to use %APPDATA%.

What version of the product are you using?

1.8.5

On what operating system?

Windows

Added Area-Pub, Triaged labels.

This does sound wrong, but just changing to %LOCALAPPDATA% may be painful to users who have globally-installed executables and so forth. One possible strategy would be to prefer %APPDATA%\.pub-cache if it exists, but start creating new caches in %LOCALAPPDATA%\.pub-cache. We could even have pub cache repair move from the old location to the new one.
