flutter_release

A tool for building and publishing Flutter apps, e.g. on GitHub, the Google Play Store and Apple's App Store. See also the according GitHub action.

Example

Build:

flutter_release build apk \
 --app-name example \
 --app-version v0.0.1-alpha.1 \
 --build-arg=--dart-define=API_URL=https://example.com \
 --build-arg=--dart-define=API_KEY=12345678

Publish:

flutter_release publish android-google-play \
 --dry-run \
 --stage internal \
 --app-name wrestling_scoreboard_client \
 --app-version v0.0.1-alpha.1 \
 --build-arg=--dart-define=API_URL=https://example.com \
 --build-arg=--dart-define=API_KEY=12345678 \
 --fastlane-secrets-json-base64=$(base64 --wrap=0 android/fastlane-secrets.json) \
 --keystore-file-base64=$(base64 --wrap=0 android/keystore.jks) \
 --keystore-password=<mykeystorepassword> \
 --key-alias=<mykeyalias>

If the command is not found (in the PATH), try: dart pub global run flutter_release ....

Note that you have to pass the base64 arguments without any newline characters:

MY_BASE_64=$(base64 --wrap=0 /myfile)

Or remove them afterward:

MY_BASE_64="${MY_BASE_64//$'\n'/}"

Options:

• app-name: The name of the app executable
• app-version: Semantic version of the release (like v1.2.3), see https://semver.org/
• build-number: Specify the build number (also used as version code for Android, but is handled automatically)
• build-type: Release one of the following options: apk, web, ipk, macos, windows, debian
• build-arg: Add options such as --dart-define to the flutter build command

Setup

Android - Google Play Store (via Debian only)

1. Create an App in your Google Play Console.
2. Make sure you have these files ignored in your ./android/.gitignore:

   key.properties
   **/*.keystore
   **/*.jks
   
   # Google Play Store credentials
   fastlane-*.json
   play-store-credentials.json
   

3. Configure signing in gradle. This is needed to be able to execute the build via Flutter and not via Gradle. Convert the keystore to a base64 string e.g. base64 --wrap=0 android/keystore.jks
4. Follow the guide of fastlane for setting up supply.
5. Convert the Google Play Store credentials json to base64 e.g. base64 --wrap=0 android/fastlane-secrets.json
6. Manually build a signed app bundle and publish it on the Google Play Store at least once to be able to automate the process, e.g.:

   flutter build appbundle \
    --release \
    --build-name=0.0.1-beta.10 \
    --dart-define=API_URL=https://example.com \
    --dart-define=API_KEY=12345678
   

iOS - App Store

1. Make sure you have these files ignored in your ./ios/.gitignore:

   *.cer
   *.certSigningRequest
   *.mobileprovision
   *.p12
   *.p8
   

2. Create an App Store connect API Team key with App Manager permissions. Copy the key into your ios folder. Also copy the Key ID and the Issuer ID for later.
3. Execute flutter_release prepare ios. Follow the steps. To delete existing certificates, visit: https://developer.apple.com/account/resources/certificates/list
4. Make sure the certificate is selected in the App Store provisioning profile
5. Extract the information from the ios/fastlane/Appfile file.
6. Run flutter_release

   flutter_release publish ios-app-store \
    --dry-run \
    --app-name wrestling_scoreboard_client \
    --app-version v0.0.1-alpha.1 \
    --build-arg=--dart-define=API_URL=https://example.com \
    --build-arg=--dart-define=API_KEY=12345678 \
    --apple-username=<apple_id> \
    --api-key-id=<api-key-id> \
    --api-issuer-id=<api-issuer-id> \
    --api-private-key-base64=<api-private-key> \
    --content-provider-id=<itc_team_id> \
    --team-id=<team_id> \
    --distribution-private-key-base64=<distribution-private-key>
   

   Optionally add the --team-enterprise flag, if your team is in the Apple Developer Enterprise Program.

Web - Server (via Debian only)

1. Generate a key pair on your client ssh-keygen -t ed25519 -f $HOME/.ssh/id_ed25519_flutter_release -C flutter_release without a passphrase
2. Add the output of cat $HOME/.ssh/id_ed25519_flutter_release.pub to your servers $HOME/.ssh/authorized_keys
3. Convert the private key to a base64 string e.g. base64 --wrap=0 $HOME/.ssh/id_ed25519_flutter_release
4. Run flutter_release

   flutter_release publish web-server \
    --dry-run \
    --app-name wrestling_scoreboard_client \
    --app-version v0.0.1-alpha.1 \
    --build-arg=--dart-define=API_URL=https://example.com \
    --build-arg=--dart-define=API_KEY=12345678 \
    --host=host.example.com \
    --path=/var/www/html \
    --ssh-port=22 \
    --ssh-user=<user> \
    --ssh-private-key-base64=<private-key>
