If you are using this image with GitLab pipeline, you can generate an code coverage report
Make your .gitlab-ci.yml looks like the example bellow

tests:
  image: alvarocda/flutter
  stage: test
  script:
  - flutter analyze
  - flutter test --coverage  # Test app and generate the coverage file
  - lcov --list coverage/lcov.info # Parse the file to genhtml
  - genhtml coverage/lcov.info --output=coverage # Generate detailed report
  artifacts:
    paths:
    - coverage # Upload the report so you can download and view

To show the percentage of covered code in GitLab

• Go to project settings
• Open CI / CD option
• General Pipelines
• In Test coverage parsing put the following regex:

\s*lines\.*:\s*([\d\.]+%)
