.dart_tool cache

[furaiev]

Hello, thank you for you package,

It looks like caching ignores .dart_tool folder. In a multipackaged project event pub get takes a lot of time and I would like to run this command once and cache the result for reuse in other actions.
Is it possible to add .dart_tool in cache?

Hi @furaiev, you can use https://github.com/marketplace/actions/cache for this.
