GitLab - analyze command failing

I want to run dart analyze and flutter analyze commands as part of my ci process (gitlab) using this gitlab-ci.yml file:

before_script:
  - apt-get update -qy
  - apt-get install -y apt-transport-https
  - sh -c 'wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'
  - sh -c 'wget -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'
  - apt-get update -qy
  - apt-get install -y dart
  - apt-get install -y xz-utils
  

  # Install Flutter
  - git clone https://github.com/flutter/flutter.git -b stable --depth 1
  - export PATH="$PATH:`pwd`/flutter/bin"

dart_analyze:
  stage: analyze
  script:
    - flutter pub get
    - dart analyze

flutter_analyze:
  stage: analyze
  script:
    - flutter pub get
    - flutter analyze

As you can see dart analyze command starts to run (screenshot taken from the pipeline while running)

After that, I will get this error:

    **More errors in here, and the end of the errors will display those lines:**

I checked locally that everything is okay when running dart analyze and flutter analyze:

What could be the problem ?

In the end I found the correct syntax :

code_quality:
  stage: test
  image: ghcr.io/cirruslabs/flutter:stable

  before_script:
    - flutter pub get

  script:
    - flutter analyze
    - flutter test
