Question 1

How do I cache Flutter dependencies with flutter-action?

Accepted Answer

Set cache: true and pub-cache: true in the action inputs. Use outputs like PUB-CACHE-HIT to skip steps like melos bootstrap, as shown in the README's caching example with conditional execution.

Question 2

flutter-action vs manual Flutter setup in GitHub Actions

Accepted Answer

flutter-action automates version management and caching, reducing boilerplate code. Manual setup might be simpler for one-off scripts but lacks integrated caching and the flexibility to handle channels, versions, and patches easily.

Question 3

How to build an iOS app using flutter-action?

Accepted Answer

Use a macOS runner (e.g., macos-latest) and follow the README example: set up Flutter, run flutter pub get and tests, then build with flutter build ios --release --no-codesign. Ensure the runner supports iOS development requirements.

Question 4

Can I use a custom Flutter fork with this action?

Accepted Answer

Yes, specify the git-source input with the repository URL, such as https://github.com/join-the-flock/flock.git. This allows using alternative Flutter distributions for specific needs like HarmonyOS support or experimental features.

Question 5

How to apply a patch to Flutter in CI with flutter-action?

Accepted Answer

After setting up Flutter, use curl to download the patch and git apply within the FLUTTER_ROOT directory, as demonstrated in the README. This is useful for applying fixes from pull requests before they are merged upstream.

Question 6

What versions of Flutter does flutter-action support?

Accepted Answer

It supports all channels (stable, beta, master) and versions via exact numbers (e.g., 3.19.0), ranges (e.g., 1.22.x), or git references (e.g., commit hashes). Examples in the README show how to specify these.

Question 7

How to use dry-run mode in flutter-action?

Accepted Answer

Set dry-run: true in the action inputs to get outputs like cache paths and version info without installing Flutter. This is useful for debugging cache configurations or planning workflows, as shown in the outputs section.
