Prerequisites:
* Understand what [Fastlane](https://fastlane.tools/) is and how it works
* Project builds correctly following these [docs](https://flutter.dev/docs/deployment/cd)
* Android app setup in [Google Play Console](https://developer.android.com/distribute/console)
* iOS app setup in [AppStore Connect](https://appstoreconnect.apple.com/)
* [Flutter is installed](https://flutter.dev/docs/get-started/install) and your project is created
1. Open your Flutter project
1. Run: cd ios
1. Run: fastlane init and follow the prompts
1. Replace the Fastfile contents with this:
```bash
#!/bin/bash
echo "App Release Automator by @rodydavis"
action="$1"
red=`tput setaf 1`
green=`tput setaf 2`
reset=`tput sgr0`
if [ ${action} = "build" ]; then
echo "${green}Generating built files.. ${reset}"
flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs
pub global activate pubspec_version
git commit -a -m "Build $(pubver bump patch)"
echo "${green}Building Project...${reset}"
find . -name "*-e" -type f -delete
flutter format .
flutter clean
echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"
echo "${green}Building APK...${reset}"
flutter build apk
echo "${green}Builing IPA..${reset}"
cd ./ios && pod install && pod repo update && cd ..
flutter build ios
git commit -a -m "Project Rebuilt"
elif [ ${action} = "beta" ]; then
echo "${green}Generating built files..${reset}"
flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs
pub global activate pubspec_version
git commit -a -m "Beta $(pubver bump patch)"
echo "${green}Building Project...${reset}"
find . -name "*-e" -type f -delete
flutter format .
flutter clean
echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"
echo "${green}Building APK...${reset}"
flutter build apk
echo "${green}Sending Android to Beta...${reset}"
cd ./android && fastlane beta && cd ..
echo "${green}Builing IPA..${reset}"
flutter build ios
echo "${green}Sending iOS to Beta..${reset}"
cd ./ios && fastlane beta && cd ..
git commit -a -m "Sent to Beta"
elif [ ${action} = "release" ]; then
echo "${green}Generating built files..${reset}"
flutter packages pub run build_runner clean
flutter packages pub run build_runner build --delete-conflicting-outputs
pub global activate pubspec_version
git commit -a -m "Production $(pubver bump minor)"
echo "${green}Building Project...${reset}"
find . -name "*-e" -type f -delete
flutter format .
flutter clean
echo "${green}Project Size: $(find . -name "*.dart" | xargs cat | wc -c)${reset}"
echo "${green}Building APK...${reset}"
flutter build apk
echo "${green}Sending Android to Production...${reset}"
cd ./android && fastlane release && cd ..
echo "${green}Builing IPA..${reset}"
flutter build ios
echo "${green}Sending iOS to Production...${reset}"
cd ./ios && fastlane release && cd ..
git commit -a -m "Sent to Production"
fi
echo "${green}Successfully completed${reset}"
```
5. Run: cd .. && cd android
6. Run: fastlane init and follow the prompts
7. Replace the Fastfile contents with this:
```bash
# Uncomment the line if you want fastlane to automatically update itself
# update_fastlane
default_platform(:android)
platform :android do
desc "Prepare and archive app"
lane :prepare do |options|
#bundle_install
Dir.chdir "../.." do
sh("flutter", "packages", "get")
sh("flutter", "clean")
sh("flutter", "build", "appbundle", "--release")
end
end
desc "Push a new beta build to Google Play"
lane :beta do
prepare(release: false)
upload_to_play_store(
track: 'beta',
aab: "../build/app/outputs/bundle/release/app.aab"
)
add_git_tag(
grouping: "fastlane-builds",
prefix: "v",
build_number: android_get_version_code
)
push_to_git_remote
end
desc "Push a new release build to the Google Play"
lane :release do
prepare(release: true)
upload_to_play_store(
track: 'production',
aab: "../build/app/outputs/bundle/release/app.aab"
)
add_git_tag(
grouping: "release",
prefix: "v",
build_number: android_get_version_name
)
push_to_git_remote
end
end
```
8. Run: fastlane add_plugin versioning_android and enter your password if needed
9. Run: cd ..
Now you are ready to launch your app to beta!
For ios run: cd ios && fastlane beta
For android run: cd android && fastlane beta
Stay tuned for an article soon where we use these fastlane sub folders for automating the releases on [Github Actions](https://github.com/features/actions) CI
