GitHub Actions ./gradlew build job succeed but does not create build directory

I am trying to make CI process with GitHub Actions for Android project. Before making a real process, the goal is to build gradle and debug apk file automatically.
The job succeed for each step, however, neither build directory nor apk file is being created.
I read various posts and tried each post suggests, but nothing gave me a solution.
What part do I need to change to get the desired result?
Firstly, Below is log I got from ./gradlew build command. It says that the process definitely has gotten into :app:build
> Task :app:lintDebug
> Task :app:lint
> Task :app:check
> Task :app:build
BUILD SUCCESSFUL in 1m 22s
And here is a GitHub Actions Job I made.

github actions flutter gives error 'Artifact pattern :build/app/outputs/apk/release/*.apk did not match any files'

I created GitHub actions to run to build apk on macOS. but it gives me warning that Artifact pattern :build/app/outputs/apk/release/*.apk did not match any files.
This is a public repo, can someone please help me here. in official docs it says the same path and locally i can build apk successfully (on windows machine).
I used MacOS to generate iOs App which i'll do later.

Your workflow doesn't build the APK, and therefore, there's no build/app/outputs/apk/release/*.apk file. So the release action doesn't find the location of the artifacts. Here is the workflow you can use to modify yours and tweak it as you wish:
# This is a basic workflow to help you get started with Actions
name: Build Flutter APK
# Controls when the workflow will run
on:
# Triggers the workflow on push or pull request events but only for the "develop" branch
push:
branches: ["develop"]
tags:
- "v*"
# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
# This workflow contains a single job called "build"
build:
# The type of runner that the job will run on

What values I should configure in my github actions secrets in order to sign my apk?

According to this answer I should run te following command in order to build an apk and sign it?
./gradlew assembleRelease -Pandroid.injected.signing.store.file=$KEYFILE -Pandroid.injected.signing.store.password=$STORE_PASSWORD -Pandroid.injected.signing.key.alias=$KEY_ALIAS -Pandroid.injected.signing.key.password=$KEY_PASSWORD
And using the android studio I made the following key configuration that is used for building the app:
The generated files in /home/pcmagas/Kwdikas/androidKeys/h330s_fu is contained using the following 2 files:
h300s_fu
private_key.pepk
And the action responsible for building and signing the apk is:
name: pr
on:
push:
branches: [master]
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Checkout latest code
uses: actions/checkout#v1
- name: Set up JDK 8
uses: actions/setup-java#v2
with:
java-version: '8'
distribution: 'adopt'
- name: Make gradlew executable
run: chmod +x ./gradlew
- name: test
run: ./gradlew test
- name: build
run: ./gradlew buildRelease
- name: Assemble Release Bundle
run: ./gradlew assembleRelease
Hence the environmental variables:
$KEYFILE
$STORE_PASSWORD
$KEY_ALIAS
$KEY_PASSWORD
Must be configured with github secrets. But what values should I configure for them? I mean what role has the h300s_fu file and the private_key.pepk one?

Fastlane + Github Actions: Couldn't find gradlew at path

I'm trying to implement a CI/CD workflow for Flutter using Github Actions and Fastlane. But, when the lane is executing throws the following error:
I create the Fastlane folder inside the android folder. Like the image
This is the content of my Fastfile:
update_fastlane
default_platform(:android)
platform :android do
desc "Deploy to closed beta track"
lane :closed_beta do
begin
gradle(task: "clean")
gradle(
task: "bundle",
build_type: 'Release'
)
upload_to_play_store(
track: 'Closed beta',
aab: '../build/app/outputs/bundle/release/app-release.aab',
skip_upload_metadata: true,
skip_upload_images: true,
skip_upload_screenshots: true,
release_status: "draft",
version_code: flutter_version()["version_code"],
)
end
end
end
And my GitHub action workflow that allows to make the build and deployment is like below. The Run Fastlane step is the error point

I have the same issue and what I found that gradlew is excluded in .gitignore inside /android folder of your flutter project.
While following runs on your local machine, it won't run Github runner:
gradle(task: "clean")
gradle(
task: "bundle",
build_type: 'Release'
)
Consider deleting lines above from Fastfile as you already do build on Github
behalf here:
name: Build the APK
run: flutter build apk

Add artifact from github actions to releases

So im trying to implement a release section on my yml file for a generated artifact, explaining myself: i would like to add an artifact to my releases with my yml file.
Here's the only yml file am working on for an android app:
name: Android CI
on:
push:
branches: [ master ]
pull_request:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- run: mkdir -p app/build/outputs/apk/release
- run: echo hello > app/build/outputs/apk/release/app-release-unsigned.apk
- uses: actions/upload-artifact#v2
with:
name: my-artifact
path: app/build/outputs/apk/release/app-release-unsigned.apk
- name: set up JDK 1.8
uses: actions/setup-java#v1
with:
java-version: 1.8
- name: Permition Gradlew
run: chmod +x gradlew
- name: Build Gradlew
run: ./gradlew assembleRelease

The actions/upload-artifact#v2 Action is meant for uploading artifacts to GitHub Actions workflow runs, not for adding assets to a GitHub release. If you want to add build assets to a GitHub release, you should instead use the softprops/action-gh-release example described here. I've modified the example to match your specific scenario:
on:
push:
# Sequence of patterns matched against refs/tags
tags:
- 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10
name: Upload Release Asset
jobs:
build:
name: Upload Release Asset
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout#v2
- name: Build project
run: |
mkdir -p app/build/outputs/apk/release
echo hello > app/build/outputs/apk/release/app-release-unsigned.apk
- name: Release with Notes
uses: softprops/action-gh-release#v1
with:
files: app/build/outputs/apk/release/app-release-unsigned.apk
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
You can repeat the final step as needed with different paths for adding further artifacts to the release.
