We need to write gitlab CI/CD to automatically increase the android app version in major.minor.patch.
We are using flutter to build & to deploy we are using fastlane.

Below is my current CI/CD:-

stages:

• build-aab
• upload-playstore

build-android:
stage: build-aab
tags:
– mobile
script:
– flutter pub get
– flutter build appbundle
artifacts:
paths:
– build/app/outputs/bundle/release/app-release.aab
expire_in: 30 day
only:
– test

upload-to-playstore:
stage: upload-playstore
tags:
– mobile
script:
– ls -lart
– export LC_ALL=en_US.UTF-8
– export LANG=en_US.UTF-8
– cd android
– fastlane deploy_beta
only:
– test

We have try find the way to automate version increase but not able to find a way.
