Deploying a Flutter App to App Store and Google Play with Fastlane

I have been using fastlane on a couple of react-native projects where it’s been a great tool which saved deployment time on both iOS and Android platforms. The configuration of fastlane for a Flutter app is quite simple and pretty the same as for the react-native. I have been following this doc on the flutter website: https://flutter.dev/docs/deployment/cd

After installing fastlane (gem install fastlnane / brew install fastlane) just make sure your Flutter project builds on both iOS and Android platforms and then initialize fastlane by typing the following command for each platform ([project directory]/ios and [project directory]/android):

fastlane init

Setting up Fastlane on iOS

#3 option

Enter your Apple Id credentials:

I have selected n for metadata since I don’t need to manage it using fastlane.
