Flutter in Gitlab CI\Cl

Medium Article

If you want to get Flutter output in Gitlab Ci\Cl this articla is for you.

I want to explain how you can get Flutter ouput by Docker Image.

NOTE: If you are new in gitlab CI\Cl you can read this, to know why should we use it.

NOTE: If you are new in docker you can read this.

Getting Started

As you read before you should add a .gitlab-ci.yml file to root of project. Gitlab will read this file to execute and get flutter output. It needs Java & Flutter SDK for woking, so we will add them by a docker image and you can use flutter commands easily. In this project I use my flutter docker image that exists in dockerHub. If you want know how I prepare it you can see this Github repository .

You should add this in first line of .gitlab-ci.yml file: image: mahdigharooni/flutter:latest

and now you can introduce your stages and what Gitlab should do . In mine I want to get a debug apk in develop branch and keep it in artifacts:

image: mahdigharooni/flutter:latest

stages:
  - build

flutter_build:
  stage: build
  before_script:
    - flutter channel stable
    - flutter upgrade
    - flutter pub get
    - flutter clean
  script:
    - flutter analyze
    - flutter build apk --debug
  artifacts:
    paths:
      - build/app/outputs/apk/debug/app-debug.apk
  only:
    refs:
      - develop

you can change it as your project.
