GitHub Actions + Flutter

I am now able to Build and Release Flutter projects.
There are a few things that have stumped me, so I’ll try to write about them here.
*It was still in beta at the time, so it may be improved in the future.

Stumbling Points.

Applying the Dart workflow to a Flutter project doesn’t work.

I somehow set up the following workflow. However, it did not work.
I needed to set up a workflow for Flutter.

Currently, the following flutter-action seems to be a good way to set up the environment for Flutter.

I don’t understand the secrets.GITHUB_TOKEN used when releaase

GITHUB_TOKEN suddenly appears in yaml, I don’t understand.

    - name: Push APK to Releases
      uses: ncipollo/release-action@v1
      with:
        artifacts: "build/app/outputs/apk/release/*.apk"
        token: ${{ secrets.GITHUB_TOKEN }}

The official documentation stated that GitHub automatically generates GITHUB_TOKEN.

GitHub automatically creates a GITHUB_TOKEN secret to use in your workflow.

But since you go to the trouble of specifying it in yaml, you really have to specify it somewhere on GitHub, don’t you? I was skeptical.
The result was that it was automatically generated, so it worked even if I didn’t pay attention to it.
Sorry for my doubt.

I can’t get Marketplace search to work.

I searched “ncipollo/release-action” on GitHub Marketplace to release it, but it didn’t come up.
I searched for “release” and it came up. The official name was “Create Release.
I hope this naming confusion will improve as the GitHub Actions ecosystem matures.

Why did I decide to use this ACTION?

The reason I decided to use the above action was because it was linked from the official Flutter documentation.
There may be other good Release actions.

GitHub Actions (beta) can now be used to Build/Release Flutter projects.
It’s nice that GitHub itself, which manages source code, has CI/CD functionality.
