How to integrate with caching

[niccokunzmann]

For caching, I see this section:

Integration with actions/cache:

What I do not know is the following:

• Is that all the code that I need?
• Do I need to configure caching paths before this?
• What benefit does it have to cache?
• Is caching enabled by default or not?

If you want to take advantage of caching, you just need to set cache: true:

- name: Set up Flutter
  uses: subosito/flutter-action@v2
  with:
    channel: stable
    flutter-version: 3.19.0
    precache: true # <--

Uh, I just created #284 and I wonder what the difference between precache and cache is.

[bartekpacia]

Ugh, my bad!

[bartekpacia]

I meant this:

- name: Set up Flutter
  uses: subosito/flutter-action@v2
  with:
    channel: stable
    flutter-version: 3.19.0
    cache: true # <--

precache is still WIP: https://github.com/subosito/flutter-action/pull/276

This might be a stupid question on a closed issue, but what exactly does cache: true do? I don't seem to see any improvements in build time :/

[bartekpacia]

Not a stupid question at all:). cache:true makes subosito/flutter-action use actions/cache under the hood (source link) to cache (1) Flutter SDK installation and (2) Pub dependencies.

I don't seem to see any improvements in build time :/

I guess this is because archiving cache + sending cache to github and (in a subsequent workflow run) downloading cache from github is not necessarily much faster than just downloading everything from Google servers every time.

If you don't see any improvement, feel free to disable it.
