Prerequisites:
Understand what Fastlane is and how it works
Project builds correctly following these docs
Android app setup in Google Play Console
iOS app setup in AppStore Connect
Flutter is installed and your project is created
Open your Flutter project
Run: cd ios
Run: fastlane init and follow the prompts
Replace the Fastfile contents with this:
#!/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}"

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 "${green}Sending Android to Production...${reset}"
cd ./android && fastlane release && cd ..

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}"Run: cd .. && cd android
Run: fastlane init and follow the prompts
Replace the Fastfile contents with this:
# 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
endRun: fastlane add_plugin versioning_android and enter your password if needed
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 CI
