7. Update Fastlane Fastfiles for iOS and Android and Change accordingly for each platform 

Make sure to change "YOUR PROJECT PATH" to the path to your project in Finder.

Only copy the correct platform code for each Fastfile. For example, default_platform(:ios) for iOS and `default_platform(:android)1st for Android.

update_fastlane

default_platform(:ios)

platform :ios do desc "Push a new beta build to TestFlight" lane :beta do increment_build_number(xcodeproj: "Runner.xcodeproj") build_app(workspace: "Runner.xcworkspace", scheme: "Runner") upload_to_testflight(skip_waiting_for_build_processing: true) end desc "Push a new release build to the App Store" lane :release do
increment_build_number(xcodeproj: "Runner.xcodeproj") build_app(workspace: "Runner.xcworkspace", scheme: "Runner") upload_to_app_store(submit_for_review: true, automatic_release: true, skip_screenshots: true, force: true, skip_waiting_for_build_processing: true) end end

//YOUR PROJECT PATH > android > fastlane > Fastfile default_platform(:android)

platform :android do desc "Runs all the tests" lane :test do gradle(task: "test") end

desc "Submit a new Build to Beta" lane :beta do gradle(task: 'clean') increment_version_code sh "cd YOUR PROJECT PATH && flutter build apk" upload_to_play_store( track: 'beta', apk: '../build/app/outputs/apk/release/app-release.apk', skip_upload_screenshots: true, skip_upload_images: true ) # crashlytics end

desc "Deploy a new version to the Google Play" lane :deploy do gradle(task: 'clean') increment_version_code sh "cd YOUR PROJECT PATH && flutter build apk" upload_to_play_store( track: 'production', apk: '../build/app/outputs/apk/release/app-release.apk', skip_upload_screenshots: true, skip_upload_images: true ) end end

• For Android increment_version_code  install here.

Sometimes it will fail and you will need to run:

bundle exec fastlane add_plugin increment_version_code

• For iOS increment_build_number set up Generic Versioning by enabling the agvtool.

8. Metadata (Optional) 

• For iOS you can have Fastlane download all your apps existing metadata including screenshots from iTunes Connect. In terminal navigate to the project and run.

fastlane deliver download_metadata && fastlane deliver download_screenshots

• For Android you can use Fastlane Supply.

9. Open Automator 

Right now everything is working just by the command line. If you navigate to your project in terminal by adding "cd " and dragging in the project folder and hitting Enter, you can type "cd ios && fastlane beta" or "cd android && fastlane beta" and both will run fastlane.

If you want to be able to submit your app to Google Play and the App Store with one click we will be using Automator. Create a new Automator Application. And Search for "Ask for Confirmation" and "Run AppleScript" and drag in.

Here is the Script for beta and release. You will need to create a Automator Application for both Beta and Release for each app you want automated. Save it where ever you want and create an Alias to be but on the Desktop.

• Make sure to change YOUR PROJECT PATH to the path to your project in Finder

Hint: I have my automator application save in the Github Repo of my project for versioning and easy access for different projects.

//Beta on run {input, parameters} tell application "Terminal" activate do script "cd YOUR PROJECT PATH/android && fastlane beta && cd YOUR PROJECT PATH/ios && fastlane beta" end tell tell application "System Events" try set visible of application process "Terminal" to false end try end tell end run

//Release on run {input, parameters} tell application "Terminal" activate do script "cd YOUR PROJECT PATH/android && fastlane deploy && cd YOUR PROJECT PATH/ios && fastlane release" end tell tell application "System Events" try set visible of application process "Terminal" to false end try end tell end run

10. Try It Out! 

Everything should be working now. If you double click on the automator application you should get a confirmation pop up to release the app. The Script will run terminal in the background and you can stay focused on developing awesome flutter applications. If you want to see the progress on fastlane uploading your apps you can click on the terminal icon and the terminal window will reappear.
