Workflows used at ZWEIDENKER to build and deploy Flutter Apps.

Melos Quality Checks

quality:
uses: zweidenker/flutter_workflows/.github/workflows/melos_quality_checks.yaml@v2with:
setup: truelint: falsetest: true

Performs quality checks for repositories using melos

Inputs

Name	Type	Description	Default	required
setup	boolean	Should run melos run setup	true
lint	boolean	Should run melos run lint:all	true
test	boolean	Should run melos run test:coverage:all	true
runner	string	Github actions runner	ubuntu-latest
lfs	boolean	Enable git lfs	false

Build Android

build_android:
needs: qualityuses: zweidenker/flutter_workflows/.github/workflows/build_android.yaml@v2with:
appDirectory: packages/appbuildApk: falsebuildBundle: trueupload: ${{ github.ref_name == 'main' }}secrets:
additionalBuildArguments: --dart-define=API_KEY=${{ secrets.API_KEY }}keyStore: ${{ secrets.ANDROID_KEYSTORE }}keyStorePassword: ${{ secrets.ANDROID_KEYSTORE_PASSWORD }}keyPassword: ${{ secrets.ANDROID_KEY_PASSWORD }}keyAlias: ${{ secrets.ANDROID_KEY_ALIAS }}googleApiKey: ${{ secrets.GOOGLE_API_KEY }}

Setup

In order to setup signing the app's build.gradle needs to contain the following blocks.

...
def keystoreProperties =newProperties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load(newFileInputStream(keystorePropertiesFile))
}
android {
...
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
...
}

Also in /path/to/app/android/fastlane/Fastfile there should be the following lane

desc"Deploy App to Internal Google Play Track"lane:uploadAppdo |options|
supply(aab: "../build/app/outputs/bundle/release/app-release.aab",json_key_data: ENV['GOOGLE_UPLOAD_KEY'],track: "internal")end

⚠️ Note that GOOGLE_UPLOAD_KEY is accessed using ENV and not through options

Inputs

Name	Type	Description	Default	required
appDirectory	string	Directory where the app is based on the repository root. eg packages/app		*
buildApk	boolean	Should build an Apk	true
buildBundle	boolean	Should build an App Bundle	true
upload	boolean	Should upload the App to Google Play. Note this will also check if the current workflow does not run on a pull_request event	false
archiveArtifacts	boolean	If the workflow should archive apks and aabs. This normally should only be needed for a first release build to upload manually to Google Play or for certain PRs	false
runner	string	Github actions runner	ubuntu-latest
lfs	boolean	Enable git lfs	false
buildNumberOffset	number	An Offset used to generate the BuildNumber. This will result in the build number being the offset + the Run Number of Github. This is only required if there are already builds on the Play Store in order to have an increasing Build Number.	0

Secrets

Name	Description	required
additionalBuildArguments	Arguments that will be appended to the flutter build command. e.g --dart-define
keyStore	Android Signing Key. Encoded as a base64 String	*
keyStorePassword	Keystore Password	*
keyPassword	Key Password	*
keyAlias	Key Alias	*
googleApiKey	Google Play Service Account json key used to upload. Information on how to optain this can be found here

Build iOS

build_ios:
uses: zweidenker/flutter_workflows/.github/workflows/build_ios.yaml@v2with:
appDirectory: packages/appfastlaneEnv: appupload: ${{ github.ref_name == 'main' }}secrets:
additionalBuildArguments: --dart-define=API_KEY=${{ secrets.API_KEY }}matchPassword: ${{ secrets.MATCH_PASSWORD }}apiKey: ${{ secrets.IOS_API_KEY }}matchSSHKey: ${{ secrets.MATCH_GIT_PRIVATE_KEY }}

Setup

For the pipeline to work the following fastlane configurations must be met

There is a valid Matchfile under path/to/app/ios/fastlane/Matchfile

The following lanes are defined in path/to/app/ios/fastlane/Fastfile

lane:certificatesdo |options|
setup_ci()api_key_path=ENV['IOS_API_KEY']match(type: "appstore",readonly: true)enddesc"build app"lane:buildAppdo |options|
setup_ci()gym(export_options: "fastlane/export_options/app-store.plist",output_directory: 'build',)enddesc"upload to testflight"lane:uploadAppdo |options|
upload_to_testflight(ipa: "build/Runner.ipa",api_key_path: ENV['IOS_API_KEY'],app_identifier: ENV['APP_IDENTIFIER'],skip_waiting_for_build_processing: true)end

⚠️ Note that IOS_API_KEY is accessed using ENV and not through options

⚠️ Note that the certificates and buildApp lane contain calls to setup_ci() to ensure proper keychain management
